You don’t need a technical architectural drawing — just something to show how a room is organized. To save you time, we have prepared a list of online tools that you can use for simple 2D floor plans. (You can also use our free online tool by clicking here. You don’t even need to go through any sign up process. Just start using the tool.)

Step 1: Understand Your Objective

There are many reasons why you might want to draw a floor plan. You may want to help explain the layout to a prospective tenant or buyer, or you may want to think through remodeling options or to figure out where to place furniture. In all of these cases, a a diagram is used to visually explain how the space can be used.

A basic floor plan is not an engineering drawing that an architect or engineer would use. Such a plan will not enable you to build a house or plan extensive remodeling. A simple layout is generally based on a layman’s sketch and can communicate ideas to a contractor or prospect. It could serve as one of the inputs for someone to prepare an architectural drawing. Simple floor plans give a general picture at a high level.

Step 2: Select a Floor Plan Tool that Just Meets Your Objective

If you have time, you can create some very elaborate renderings with elevation drawings and 3D views, but if you just need to show the basic layout of walls, windows and furniture, you should use a simpler tool. You don’t need expensive software just to draw basic shapes and lines.

Some tools will let you collaborate with other people by providing a single web page that everyone can edit, but this is an extra bit of functionality that you don’t need or want to pay for.

In other words, don’t over-engineer your solution, because that adds unnecessary cost and will take up more of your time. By using the simplest solution, you will save time and money.

High Tech Floor Plan Tools

You can convert your smart phone into a floor plan sketcher by buying apps like the following:

  • RoomScan is fully automated. You just need to hold your smartphone and walk around the room as it takes videos and then then produces a floor plan. The technology is still evolving.
  • MagicPlan is similar to RoomScan.
  • Stanley Smart Connect also allows you to take measurements and design floor plans using your smartphone.

Online Floor Plan Tools

If you’d rather do the work yourself, there are a number of online tools that will let you create scale drawings to envision your remodeling and decorating projects—and some of these tools are free:

  • DesignPresentation provides a free online floor plan creation tool that requires no registration process or download. It’s simple to use, and after you finish your floor plan you can save it on your own computer; no copy is saved on DesignPresentation’s server or anywhere else.
  • Gliffy Floor Plan Creator is a simple online floor plan tool for drawing 2D floor plans, but has no free option. Data is stored on Gliffy’s server.
  • SmartDraw is a graphics tool that can be used for floor plans, but has no free option. Data is stored on SmartDraw’s server.
  • RoomSketcher allows you to create 2D and 3D floor plans. It has a registration process, and has both free and non-free options. Data is stored on RoomSketcher’s server.
  • EZ Blueprint is a simple program for Windows computers, so you have to download it. It has a registration process, and has both free and non-free options.
  • FloorPlanner.com is an online floor plan tool. It has a registration process, and has both free and non-free options. Data appears to be stored on FloorPlanner’s server (this needs to be verified).

Step 3: Consider Issues of Privacy and Confidentiality

Many of the online tools listed above are “cloud-based,” which means that the floor plan you design is stored on someone else’s computer, not your own (DesignPresentation is an exception — the data is stored only on your computer).

Almost all the tools require some form of registration that will require you to divulge information about yourself. (DesignPresentation is again the exception).

Also, some cloud-based tools can only be viewed online. If you’d like to print out your floor plan, opt for an app that enables you to download your design onto your laptop or tablet.

You have lots of options, so before you decide which way to go, think about how you want to balance your requirements with issues of cost, privacy, convenience and simplicity.

Solar Drafting Services for Solar Permit Drawings https://www.designpresentation.com/blog/solar-drafting-services/ https://www.designpresentation.com/blog/solar-drafting-services/#respond Tue, 19 May 2020 09:11:37 +0000 https://www.designpresentation.com/?p=5168 Solar drafting services are an essential part of the solar power industry, from the moment the customer has an idea to the final installation.  Solar drawings, aka “solar permit drawings” or “solar permit plans,” form an integral part of solar permits. (See below for more details on how such permit drawings fit into the solar permit process.)

Background

Today, solar energy is emerging as a popular choice of renewable energy for residential housing, industrial buildings and commercial complexes. In fact, its an idea whose time has come: a simple, clean and renewable source of energy.

Now, solar panels with photovoltaic power systems convert sunlight directly into electricity. A solar mounting system can go either on the roof or ground (rooftop or ground-mounted). The mounting systems is a standard feature of any solar installation.

In short, a detailed solar panel layout plan serves as an essential tool for the construction and maintenance of solar arrays.

As a result, solar installation companies are major users CAD-based solar PV (photo voltaic) drafting services. Photovoltaic projects are a major driver of solar drafting services.

The Role of CAD in the Provision of Solar Drafting Services

CAD, or computer-aided drafting, is the use of computers and software to replace manual cad drafting using drawing boards. Solar array layouts, detailed roof diagrams, residential roof mounts, commercial ground mounts, car-ports, and solar farms all require CAD drawings.

In fact, CAD-based solar drafting services includes a wide range of engineering disciplines, such as electrical, mechanical, structural, and architectural.

So, what are the benefits of CAD? Installers benefit greatly from the use of CAD because they can approach a project with an idea about how to lay out a solar array. Also, a key advantage of CAD is the ability to quickly measure the electric power output of a solar project.

Of course, to design an effective solar power system, the direction of the sun is an important consideration. Solar drafting services include the use of 3D shading analysis. This helps installers determine the correct positioning of solar panels.

Read more about how Design Presentation can help you.

Use our Get-A-Quote form to submit details about your solar project.

What are solar permit drawings?

Before you install a solar power system, you’ll need to file for a permit to get approval for your project. Solar permits often require approval from two organizations— your local building authority (to approve new construction), the other from your local electric utility (to approve interconnection to the grid).

It takes time to submit detailed documentation for your solar panel system, like wiring schematics and spec sheets for each component.

Step 1: System Design & Line-Item Quote
First, you need to have a target system size and design in mind.

Step 2: Fill Out Interconnection Permit
Once you have a size and design in mind, you need to apply for an interconnection agreement, which gives you the approval to connect to the utility grid.

The utility company wants to ensure your system is safe and code compliant. To make that judgment, they’ll need to see component spec sheets and a wiring diagram to ensure everything is properly designed. 

Interconnection agreements commonly ask for the following information:
1. Location of utility meter, electrical panel(s), proposed PV array and other landmarks.
2. The number of solar panels and inverters, including manufacturer and model being installed.
3. The capacity rating for your planned power inverter and PV panels.

Step 3: Building Permit
You’ll also need to file for a building permit with your local AHJ that oversees new construction—typically, your city planning office.

If you’re building a roof-mount system, the AHJ will want to confirm your roof is engineered to handle the extra weight of the solar array. Most recently built homes are fine, but older homes may have rooftops that are damaged and/or not engineered to support extra weight. In these cases, you could either replace/repair your roof or explore the possibility of ground-mount solar instead.

If you’re unsure, it’s a good idea to have your roof inspected by an engineer before filing for a building permit. Processing applications can take some time, and a rejected permit can delay your project for days or even weeks.

Step 4: Fill out & submit both forms
Once you have tracked down both forms, it’s time to fill them out and submit them. Gather the following info to have on hand during this process:
1. Product spec sheets
2. Site map / plot plan
3. Solar panel wiring diagrams
4. Fire safety ratings
5. Engineering certifications for panels and mounting hardware
6. PV labels and placard placement map

This process is fairly time-consuming, often resulting in applications around 10-15 pages long.

3D File Fixing: What to Keep in Mind While Preparing for 3D Printing https://www.designpresentation.com/blog/3d-file-fixing/ https://www.designpresentation.com/blog/3d-file-fixing/#respond Thu, 09 Apr 2020 12:07:09 +0000 https://www.designpresentation.com/?p=5140 Printing a 3D file is not so simple — first you need to know about 3D file fixing. Here are some basics:

BACKGROUND

3D printing is a blessing for architecture as it allows us to create architectural models quickly and at a reasonable cost. One of the greatest benefits of 3D printing is that you can create scale models of all sorts of structures. It’s a great way to get your clients to see your work. The real-life perspective of working with 3D models along with being able to re-print a new design is a combination that results in immaculate accuracy while building structures in the real world.

The earlier complexity and high cost of architectural models is affected greatly with 3D printing. Integrating it into your architectural firm is easy since most firms already have an in-house design team that uses CAD applications. In such a case, you can simply connect your 3D printer to your computer, or hire a professional 3D printing service if you don’t have the required services in-house.

Elevations that were a problem in 2D are easy to create in 3D printing. You’ll be able to understand them simply by rotating the drawing, as you would a physical model.

Another wonderful thing about 3D printing is that you can avoid human errors. With the freedom to design without worrying about this, you can try new things since test models are quick, accurate and cost effective to create.

To create useful 3D models, you must master the techniques of creating 3D printed models. It is complex process but as discussed, very rewarding. It’s important to be mindful of a few things before as well as while you create a 3D print for a 3D model. Here are some of them.

SOFTWARE AND FORMATS

3D Modeling Software
Step one to create the perfect 3D print is to understand the 3D modeling software. Software applications allow you to build from scratch, or to convert a 2D model into 3D. There are over a hundred different models and you can select one based on your personal requirement. Ensure you understand all features of the software you decide to purchase. Keep in mind that some software will require certain hardware and you should make your decision based on that combination. Budget, level of expertise, scale and print size will help you take your decision. It’s important to spend the early days figuring out exactly what your requirement is so that you don’t invest in the wrong software.

File Format
The most common file format for 3D printing is Standard Triangle Language, or STL. Your design will be translated into triangles in a 3D space. While exporting the file you will need to define a tolerance for the export, defined as the maximum distance between the original shape and the STL mesh you are exporting. Try and avoid printing a tolerance less than 0.01 mm as 3D printers cannot print at this level of detail.
We’ve talked about the other file formats at the end of the article.

SHELLS AND PARTS OF THE MODEL

The Parts of your 3D Model
Shells or nodes are the components or parts of your 3D model and will be present irrespective of the software you use. They make up the final model and each model can have from a few, to a thousand shells. Experimenting and using shells that are different from what other architects use could be what makes your entire structure unique. You must understand exactly what shells are needed, and where they must go.

Ensure the Shells are Solid and Watertight
Your model will not be able to print properly if it has holes of gaps in it. Flat open surfaces will need to have some thickness. To ensure this, follow the vertex-to-vertex rule. The rule states that all adjacent triangles share two common vertices and if you don’t comply with this rule, you might end up with holes of gaps in your file. Even though it’s possible to fix this with applications, you should be able to do so manually. Either through the process of capping, or by forming a new triangle with common vertices as per the rule. Be careful of floating unused points as these would create new gaps.
Another option is to fill gaps by converting your file from one format to the other. Since converting might cause new gaps, it is better to first identify all the gaps, and then take care of them after formatting to the new format. Having many shells can help, since you can repair a faulty shell, or create a new one in case one shell is damaged and causing the problem.

Unsupported or Floating Shells
While unsupported shells are alright in virtual architectural models, they become difficult to deal with when printed. It’s important to identify any floating or unsupported shells before printing, which requires diligence. Doing so will go a long way in prevent mishaps in the final 3D printed model.

Caution against Too Many Shells
While it is completely up to you how many shells your model would need, be cautious against working with too many unnecessary shells in your structure. Your architectural model needs to be simple and clean and the best way to achieve this to use only what you need. Fewer shells are easier to manage while too many only complicate matters. Too many shells at a time of repair becomes complex too.
Fewer shells can ensure you section your model well and only print sections needed, at a maximum scale. Printing at maximum scale is good because it reduces the need for thickening.

DOUBLE CHECKING DETAILS

The Correct Polygon Count
Your geometry topology and overall polygon count are important to successfully create a 3D printable model. Try to keep the geometry clean and the polygon count to a minimum. Not only will this help avoid potential gaps, but will also minimize the model file size. But remember, the lesser the number of polygons, the more faceted the model looks so don’t just try to reduce the count and end up compromising on the quality of the model.

Positioning your ‘Normal’
Most 3D models consist of triangular polygons, each of which has three points and a ‘normal’ which is the invisible line perpendicular to the surface of the polygon. Ensure the normal is facing toward the outside of the shell. This is because normals tell the printer which way to add the material, and this way the material will be added from outwards.

Inside vs. Outside
To determine the volume of a model, most 3D modeling programs distinguish between the inside and the outside surfaces. You must double check your files to make sure all normals are facing the right direction to avoid inward-facing or reversed faces.

How Small is too Small to Print?
What is the SPF or smallest printable feature on a 3D printer? Well, it depends on the scale, overall design and complexity of the project. Some features might be too delicate to print and you can use “non-contact” fixtures to attach them to the model to prevent breakage. It will take a bit of an experienced guess to understand what features might be too delicate. You can try test-printing models to fully understand what works best for you.

Assigning Thickness to Each Wall
When shifting from visual 3D models to printed 3D models, an important addition is wall thickness. While visual 3D models don’t require them, it is important each surface in your 3D print has been assigned wall thickness. You will need to feed in information about how thick you need each wall to be, or if the model is to be entirely solid. Being careful about this can go a long way in avoiding printing problems.

PRINTING THE MODEL

Co-planar surfaces Can be Tricky
Do be careful while working with co-planar surfaces as these can cause all sorts of problems in 3D printing, particularly while working with colored or textured AEC models.

Your Printer Might Find Overlapping Confusing
Intersections or internal overlapping in your model might confuse the printer about what exactly to print. While preparing to print a model, be careful of this. Think of it in a 2 dimensional space first, to help understand the best way to deal with these intersections.

Printing Multiple Parts
While printing more than one part, upload each separate object individually. Group models are not always a good idea. If you need to print many small parts, you could consider designing a grid container for your 3D prints.

Printing the Tiny Details
Small decorative details such as engravings or embossing must be of a certain size in order to appear properly on your model. The exact minimum size would depend on the material you use to print. It’s important to ensure you stick to this so that everything is readable once printed.

EXTRA MATERIAL

Artificial Support
Speaking of SPF, what do you do about the elements of a model that you know might not survive the entire process of 3D printing?
Artificial support is a good option. These can be categorized into integrated – that eventually becomes a part of the final model – and removable – that can be removed after the finishing is complete.

Hollow vs Solid Models
If the primary aim of your model is to show off its exterior detail, save up on material by printing a hollow model. Though you will need to ensure they’re sturdy enough to not topple, they needn’t be entirely solid. Solid materials aren’t necessarily a bad thing as they will be stronger and harder to break. But they can get too heavy and more expensive to build.

Building Escape Holes
While building a hollow model, material might get trapped inside since printers print layer by layer. To fix this, incorporate escape holes in your design through which you can remove any extra material.

By being mindful of these factors, you are already closer to printing your 3D models perfectly. An important point touched upon earlier was the 3D printing file formats you can use. We’d talked about STL, but here are three others that are popular.

POPULAR 3D FILE FORMATS

Using the correct 3D file format is a crucial step as the format of your file will decide what information the 3D printer will receive. You can choose what works best for you as per each format’s specifications. Here are the four most popular ones.

STL (Standard Triangle Language)
This format is the most popular in the world, and was developed by Chuck Hull in 1987. It saves your model as a surface of geometrical shapes, turning it into a triangular mush, but does not carry information about the models texture or color. However, most people do not find this an issue.
STL ensures your model has no holes or overlaps, which is a process known as Tessellation, which can save you lots of hassle during printing.

OBJ
OBJ is short for Object and is the next most common file format. The advantage it has over STL is that it stores color, material and texture data so you can print in multicolor. Not only does it offer Tessellation, but also advanced options like free-form curves and surfaces.

The downside is that it is more complex than the STL and it is not easy to repair in this format.
OBJ file comes with an MTL file which is responsible for storing color information. It can be hard to keep track of both while transferring.

AMF (Advanced Module File)
This format was introduced by ASTM in 2013 solely with the purpose of catching up with the evolving Additive Manufacturing technology.
AMF stores information about the geometry, color, material, lattices, duplicates and orientation.
Just like STL, it turns the surfaces of 3D models into mesh. The difference is that the triangles have a sleek finish owing to the fact that the triangles can be curved.

3MF
This format too was designed for Additive Manufacturing needs, by Microsoft. They have a special body called 3MF Consortium to work the 3MF. It consists of geometries, color, materials and textures and has an open source.

Once you decide what file format works best for you, you can get started with your 3D printing. Be mindful of being thorough with your model before printing to avoid errors, but also be creative and have fun!

CAD File Formats https://www.designpresentation.com/blog/cad-file-formats/ https://www.designpresentation.com/blog/cad-file-formats/#respond Sat, 19 Oct 2019 10:07:59 +0000 https://www.designpresentation.com/?p=4896 CAD file formats are important because not all formats are interchangeable. Some formats can only be viewed in specific CAD applications. (To learn about how to convert from one CAD format to another, click here.)

Have you ever worked with CAD? If yes, you’re already likely to be familiar with some of AutoCAD’s most common file format, such as DWG and DXF. These aren’t the only file extensions and formats used with AutoCAD, though. In fact, there are some formats that many people are not entirely familiar with. What is a file format actually? Is a file format different than a file extension? If you are lost with such kinds of questions, this article is for you.

File Extension:

A file extension is a group of characters after a file name, e.g. if there is a file in Windows named ‘article,’ and you find it as ‘article.docx,’ then ‘.docx’, is the file extension. This file extension, ‘.docs’ lets Windows know that which program on your computer the file, ‘article’ can be open with. Here, extension ‘.docx’ should be open with Microsoft Word.

File Format:

Every file in a computer is created as a particular type ort format. Typically file extensions are used to determine the file format or file type. For example, if you have an extension, ‘.docx’ or ‘.doc,’ you must be dealing with Microdoft Word. Most often, an extension is associated with only one type or a more popular file format. Such as, ‘.pdf’ extension deals either with, ‘portable Document Format,’ or a ‘a printer description type.’ This is the reason the two terms, file extension and file format, are often used interchangeably.

What Is A CAD File?

CAD is an image file format used by AutoCAD, which is generated by CAD software programs and also creates 2D and 3D designs for models or architecture plans. CAD files hold information for these images; 2D CAD files are often referred to as drawings, whereas 3D files are called models, parts, or assemblies. CAD stands for Computer Aided Design.

Why is CAD File Format Important?

While creating any kind of document using a computer, you must save the same as a file. This file contains all the necessary information related to the document as well as the way it should be processed and visualized.

CAD file formats are also extremely important when considering CAD design. When using programs such as AutoCAD or SolidWorks, you are creating a digital document. This document is then saved as a specific type of file format.

CAD file format apprises which program you can use to view the document. Moreover, it informs about the content of the document. For a CAD file, that means the design itself.

Each CAD system has its own method of describing geometry, both mathematically and structurally. CAD files hold information for these processes, as well as drafting information.

As mentioned above, there are 2 dimensional (2D) and 3 dimensional (3D) file formats. As the name suggests, in a 2 dimensional system you are operating under 2 axes only. The resulting file is a layout/draft of the object being designed.

In a 3 dimensional (3D) environment the object is more visual as we have added another axis into the system. The objects seem real and curvatures, texture and all complex surface features are easily visible.

Usually components are designed in a 3D environment and production is conveyed in 2D format called production drawings. Latest production techniques can work from the 3D data itself which is called CAM (Computer Aided Manufacturing).

Categories of CAD File Formats:

CAD file formatting states, how the design will be viewed within a particular program such as AutoCAD or SolidWorks. There are two main categories of CAD file formats:
– Proprietary
– Non-proprietary (or neutral).

Proprietary Vs. Non-proprietary

Have you ever heard the terms, ‘proprietary goods’ and ‘non-proprietary goods?’

Proprietary goods are made and sent out by a particular company whose name is on the product. On the contrary, at its most basic definition, non-proprietary is defined as a generic good type.

What do these two terms mean in the context of CAD file formats?

There are some CAD programs, which use proprietary file formats. These are the file formats that have been created solely for use on that one program. This file is generated and coded in such a way that it can only be opened using that particular program, which is used while creating it. If you try to open a proprietary file in another program, you receive an error.

Proprietary CAD file format contains everything from the original design; nothing will be left out. This type of file is useful for sharing designs within the company and every user must have access to the same program. Hence, in this case a neutral file format is not needed.

A neutral or non-proprietary file format is not exclusive to one CAD program. It is considered as vendor neutral and can be opened in different programs that can read it. This type of CAD file format generally uses generic information and standardized protocols so that many programs will understand the contents within.

Non-proprietary or neutral CAD file formats are useful when you need to share the documents with external sources. You may, for example, wish to share a CAD product design with a customer, who has not the access to that particular CAD program. If the design is shared as a non-proprietary format, they are still able to open the file.

Most Popular Proprietary CAD File Formats:

1) SolidWorks

The SolidWorks file format is a proprietary file for the SolidWorks CAD software that runs on Windows systems. This CAD program was first released in 1995. It is one of the longest-running CAD program and still widely used throughout many industries. SolidWorks is capable of creating both 2D and 3D drawings. The proprietary SolidWorks file format is regularly used, but they have also released a popular neutral format as well.

2) Autodesk Inventor

This is another hugely popular designing program and is used to create 3D documentation and realistic scale models of parts as well as components. Moreover, this program is compatible with BIM, which is currently an exploding file format in the construction industry.

3) Solid Edge

The proprietary file format for this program is Solid Edge. The file extensions for this formats are ASM, PAR, PASM, and PWD.

Some Popular Neutral File Formats:

1) STEP

STEP is one of the most widely used CAD file format. This format is created in conjunction with ISO 10303. ISO 10303 is the standard for computer representations of product manufacturing information. Most modern CAD software supports this file format. STEP can support both single file and assembly formats. It also can contain a Bill of Materials (BOM).

2) VRML (Virtual Reality Modeling Language)

This tupe of non-proprietary file format is actually used for the representation of 3D graphics and interactive vector graphics, which is developed in conjunction with the Web3D Consortium. The VRML file format is usually used for web graphics, which can specify surface color, textures, transparency, and other important graphical concepts.

VRML and its successor X3D have become international standards (ISO). This format is first specified in 1994. X3D is approved later on in 2005. Both file formats are non-proprietary and can be opened with a variety of programs.

3) IGES

IGES (pronounced as eye-jess) is another popular non-proprietary format. This format is first developed in 1980 and widely used in the CAD industry since then. It is developed exclusively by the US Airforce, but once they have started to use other technology, the format is taken over by ANSI.

This file format is used to display wireframes and circuit diagrams. Because of its lack of color rendering and textures, it should generally not be used to share designs with third-party organizations, unless they know the design process or the product.

AutoCAD’s Common File Types: DWG and DXF

DWG:

DWG is used as an abbreviation for ‘Drawing,’ which is a proprietary vector file format created by Autodesk in 1982. Developers need a license to access this format in their software. DWG files are smaller than DXF files due to their binary makeup. Users can view and edit DWG files with other programs too, including Scan2CAD, though they are designed to be used in AutoCAD.

DXF:

Drawing Exchange Format, DXF, is a vector file format and was created by Autodesk as an exchange medium between different types of CAD software. It is an open standard, so it’s supported by practically every CAD programs in the market. You can also view DXF files using a range of programs including Adobe Illustrator and Scan2CAD. While DXFs are smaller than their raster counterparts, they’re typically larger than DWGs. Why? Because DXFs are made up of ASCII text, whereas DWGs are binary.

Some More File Formats for Sharing 2D and 3D CAD Designs:

STL:

Stereo Lithography, is a universal format. It is a format for pure 3D information that has been specifically created by 3D programs. STL is concerned with surface geometry and shapes. It cannot be used to represent color or textures. This file format is fine for use in basic situations where complicated CAD data is not required.

X3D:

X3D actually replaces the non-proprietary file format of VRML. Although, VRML was popular, yet limited to only a number of different software packages. X3D is also a neutral file format and is used to represent 3D computer graphics in an XML format. It can be used to encode graphical scenes with the XML syntax, and it allows integration with a number of different APIs as well.

PDF:

The Portable Document Format is proprietary to Adobe but has a wide array of uses. PDF files can be converted into AutoCAD files. CAD files can also be exported into PDFs for easy viewing. If you want to simply showcase a 2D design to a customer or someone without CAD knowledge, a PDF file is suitable. Many CAD programs allow you to export your work to a PDF.

Above is a list of a few file extensions that you may run into. Though it’s truly said that, “there are more CAD file formats than there are CAD design programs!”

Which Type of File Format should be used?

Now, the obvious question comes in the mind is, which type of file format should be used? The file format you should choose largely depends on the type of CAD program you’re using. You may have to use a proprietary file format. For example, you may want to work exclusively with SolidWorks, which is a proprietary format. Or you could use non-proprietary formats such as STEP.

Architects vs Draftsmen https://www.designpresentation.com/blog/architects-vs-draftsmen/ https://www.designpresentation.com/blog/architects-vs-draftsmen/#respond Fri, 20 Sep 2019 16:53:51 +0000 https://www.designpresentation.com/?p=4887 So you are thinking about the pros and cons of hiring architects vs draftsmen…

Have you made the decision to build a home? Well, what is the next step?

Of course, your next step should be designing your home, but how will that plan come about?

You could go directly to an architect, select an existing plan, or go to a home building company. If you choose the latter option, you may wonder if the company has draftsmen or professional architects on staff. Let’s review the difference between a draftsman and an architect.

Architects vs draftsmen

These two terms can be quite confusing. It may seem like they perform very similar functions. Yes, they both work in the field of construction and are expert in making designs for different building projects. However, there are some distinct differences between these two professions.

What Is Architecture?

Architecture is a passion, a vocation, a calling – as well as a science and a business. It has been described as a social art and also an artful science. Architecture must be of the highest quality of design.

The profession of designing buildings, open areas, communities, and other artificial constructions and environments, usually with some regard to aesthetic effect. Architecture often includes design or selection of furnishings and decorations, supervision of construction work, and the examination, restoration, or remodelling of existing buildings.

What Is Drafting?

Drafting refers to creating technical drawings that communicate how something is constructed or functions. Drafting is intended to have one particular meaning, which is made clear with symbols and measurements. Hence, it is different from a visual drawing such as art because visual drawing is open to interpretation.

While sketching and diagramming can both be considered drafting, AutoCAD software makes these ideas more clear and turns them into sophisticated models in either 2-D or 3-D.

Who is an Architect?

An architect is a professional, who designs and builds structures for people to work, live, eat, shop, and worship in. Here, structures include office buildings, homes, schools, and complexes for outdoor, indoor, public, or private use. Architects must also make sure buildings are functional, safe, and economical. They are involved in every phase of the project, from planning to completion.

Architects use computer-aided design (CAD) software along with building information modelling (BIM) to render construction drawings. They must ensure these designs adhere to ordinances like zoning laws, fire regulations, and building codes. Architects must also keep persons with disabilities when creating these structures to make sure it is accessible.

Who Is A Draftsman?

A draftsman is essentially trained and qualified to create to-scale technical drawings that include detailed specifications. These drawings are mostly created using CAD, or computer-assisted design software and three-dimensional representations of the object.

Draftsmen often continue their study and experience to include design and usually work with architects or engineers, depending on their expertise. They take the instructions from the engineers or architects to produce accurate templates, blueprints and 3D visual models. Draftsmen are often employed in a drafting service, and can be engaged by architects or engineers to produce blueprints for a variety of projects.

Educational Requirement For An Architecture

The educational and licensing requirements for an architect are much higher than for a draftsman. An Architect should require at least a Bachelor’s degree, but some might also have a Master’s in the field. Some course topics might be CAD, construction methods, architectural history, math, and technology. They must also gain work experience before they graduate through internships. Working architects are expected to periodically continue their education through conferences, classes, and workshops.

Educational Requirement For A Draftsman

Draftsmen obtain their education through college training and get a certificate, diploma, or associate’s degree at technical institutes or community colleges. Topics of study typically include sketching, design, and CAD. Unlike architects, draftsmen do not need to apply for licensing. They can also get certification in a specialized area.

While architects and draftsmen share some job duties, architects complete more education and must meet licensing requirements. Their level of expertise is better suited for an entire project.

Professional Advancement In Architecture:

After working for multiple years, it is possible for an architect to advance and promoted as Architectural and Engineering Managers. These jobs include greater responsibilities in terms of project coordination and employee supervision.

Professional Advancement In Drafting:

Drafters may be able to advance their job prospects by earning a professional certification from any certified institute. Drafters may become certified in a specialty area.

What To Expect From A Draftsman?

A draftsman is proficient in all aspects of technical and material designs, dimensions, and procedures. If you choose to work with a draftsman, you can expect construction-ready design drawings, technical schematics, and material design drawings. Generally you can’t expect a draftsman to have the artistic or comprehensive background to go beyond making minor changes to your plan.

What To Expect From An Architect?

You can make drastic artistic changes to your plan with the expert advice of your architect. An architect is better able to see the entire scope of your project and design to meet all your needs, contemplating not only the size of a space but how you move and live inside it. The flow of the layout, the functionality of the space, and how the architecture adds character throughout.

A draftsmen’s training is primarily focused on technical issues, while an architect is trained artistically, technically, and holistically.

How Does An Architect Work?

An architect are mainly come up with plans for the construction projects involving commercial and residential buildings and spaces. His/her responsibility is to determine the specifications and measurements of the structures to be made as well as the materials that should be used for the project. An architect also provides the details of the project’s interior and exterior designs as well as the cost of construction. He plans for the estimated time for completion of the project.

An architect must have the knowledgeable about building codes, fire ordinances and zoning restrictions. The designs should also be made to comply with these rules and regulations. He is responsible for discussing with the clients first to determine their (the clients’) plans for the project and/or any other specific design requests they (the clients) may have. Architects may even perform tasks that are not really part of designing the structure but also related to it and are done before construction commences. These include selecting the site, conducting feasibility studies and undertaking environmental impact studies.

How Does A Draftman Works?

A Draftsman or drafter, typically, translates the concepts or designs of architects to technical drawings or blueprints. Although architects are trained to make these drawings, in a real world setting, this task is often assumed by drafters. Draftsmen use Computer Aided Design and Drafting (CADD) software to come up with the technical specifications of the designs planned by the architects. Most often, architects and engineers simply come up with rough sketches of the designs that their clients want. They then communicate these to the drafters who will take care of making the schematic diagrams or outline. Schematic diagrams/outline refers to the main form and features of something, usually in the form of a drawing, which helps to interpret it.

Draftmen use their knowledge of building and construction to create very accurate drawings that are to scale. The draftsmen are also able to make three-dimensional drawings, with the help of CADD, that can be incorporated into building information modeling (BIM) systems and product data management (PDM). These software programs make it easier for drafters and architects to work together and track changes made. BIM and PDM software programs facilitate speedier progress of the project since it has made simultaneous collaboration possible. Before the advent of these programs, architects and drafters could not work together at the same time since the drawings have to be made, and then any changes reflected again in a new illustration before any discussion or approval can be given. With CADD, BIM and PDM, however, changes can be made in real time.
In a nutshell, the difference between the responsibilities of an architect and a draftsman is that an architect can do almost all types of tasks involved in building, where as drafters are specialists who focus their attention on creating beautiful designs and clear, concise drafts for the builders to follow.

Does An Architect Take longer Than A Draftsman?

Well, yes. An architect may take several months for designing the process, discussing as well as clarifying all the details with the clients, analysing the site and determining its ambience, and revising a design until fully resolved, through consultation(s) with the clients and other relevant professionals. Where as a draftsman may take just a few weeks to produce a set of drawings for construction with little emphasis placed on the context and the sense of place.

Is An Architect More Costly?

An architect’s role is much broader and time taking than that of a draftsman. This extra work at the designing stage of course has an implication on the cost. However an Architect provides long term value for money.

An Architect Over A Draftsman Or Vice-Versa?

Ultimately the choice of whether to use an Architect or a Draftsman will depend on many factors and individual client’s priorities. If the client places a high value on aesthetics, usage of space, energy efficiency, a unique or artistic look, then it’s worthy enough to invest more resources at the design phase by hiring an architect.

On the contrary, if the client is happy with a slightly modified model of any previously done design or needs to use the services of a renovation or extension company, then a draftsman is more than capable of completing the task at hand.
Relation Between An Architect And A Draftsman:

Previously, an architect designed a structure from scratch and then passed off their rough sketches to a draftsman to refine into workable drawings for actual builders. Originally this was all done on paper. Hence, draftsmen had very little to do with design decisions back then. They simply used to translate the architect’s concept into a “how-to” sort of schematic diagram on paper.

Nowadays, CAD has made construction drawings faster to create, easier to modify, and simpler to reproduce. Draftsmen of modern era are now able to design simple buildings on their own by using the templates and software assisted engineering,
Over time, as draftsmen have become more savvy with the tools of their trade, it’s been common for the structures to be conceptualised and constructed from start to finish even without ever consulting a certified architect.

Things You Need to Decide Before Developing Floor Plans https://www.designpresentation.com/blog/things-you-need-to-decide-before-developing-floor-plans-for-your-home/ https://www.designpresentation.com/blog/things-you-need-to-decide-before-developing-floor-plans-for-your-home/#respond Wed, 10 Oct 2012 12:55:05 +0000 http://www.designpresentation.com/?p=2202 The floor plan of a home is a blue print that allows the owner of the house to see area-wise allocation of each and every room of the house. Home plans usually portray a three dimensional view of the house along with the floor plans incorporated.

Floor plans are extremely crucial in various stages of making house plans, or building plans and for executing architectural designs. For a well structured and smartly designed home, it is necessary that the floor plans are well made, and the home plans are well executed.

For well made floor plans and home plans, it is necessary that various issues are considered and well thought out.

Firstly, it is important to know how the floor plans and home plans will be accommodated in the building plans. To design and know the entire structure that will be the building, building plans are also of immense importance. It is also important that the floor plans and home plans one makes are fit well into the building plans, and are compatible. This is important so as to ensure that the floor plans and home plans are not in any way disrupting any other floor plans or home plans within the building.

Second of all, people need to know the interiors that they desire for their house. To make floor plans and home plans according to the owners’ tastes is crucial, essentially because it is not easy to make and re-make floor plans or home plans, not ones that are well thought out. So, all owners should actually sit down with their architects and with him go step-by-step over the home plans fine tuning them till they get what and how they want. House plans, which are a variant of home plans, are also beneficial so as to view the interiors of the house, usually by AutoCAD virtual tours. Such house plans allow the owners to actually see different versions of their floor plans and to try out different home plans along with a variety of interiors they can choose from.

Home plans are also important as they incorporate and display to the owners their tastes and preferences in interiors. Also, house plans allow people to actually get the feel for their house, even before they live there. House plans are fast becoming and developing into an excellent advertising strategy for new houses.

Nowadays, it is easy to take a look at floor plans as they are present in real estate brochures to make the task of choosing a house easy. Home plans, however, aren’t as popular as they should be, considering they are the best way to get a feel of one’s house, with both architecture and interiors in one place.

The Benefits of 3D Modeling https://www.designpresentation.com/blog/the-benefits-of-3d-modeling-services/ https://www.designpresentation.com/blog/the-benefits-of-3d-modeling-services/#respond Wed, 10 Oct 2012 12:47:54 +0000 http://www.designpresentation.com/?p=2199 3D modelling refers to the process of establishing a mathematical representation, of any available three-dimensional object, through specifically specialized software. The product of 3D modelling is called a 3D model. A 3D walkthrough on the other hand is 3D modelling with respect to the floor plan based on the architectural design of a house.

The basic idea of a 3D walkthrough is that it creates a virtual 3D layout of the house, for the residents to peruse through, in order to see what their house will look like. 3D walkthrough is an accurate source of the house layout plan, as it is based on 3D modelling, which works on mathematical and calculative, focused software.

There are several advantages of 3D modelling of the house and of 3D walkthroughs. 3D walkthrough is also being used widely, as an online marketing tool. Since a large number of people check for information regarding houses on the internet, the 3D walkthrough provides a virtual tour on the internet itself.

The best feature of the 3D walkthrough is that the 3D modeling is done in such a way that the buyer of the house is able to visualize the house with a genuine feel of the size of the plot, and an idea of the exact layout of the house. In view of the fact that 3D walkthrough is banked on technology as advanced as 3D modeling, there is an added scope to make provisions for the would be owners of the house to effect changes to the interiors, furnishings and decorating styles of the virtual house, as per their tastes and preferences. This makes for an excellent sales strategy.

Further, 3D modeling allows 3D walkthrough to be quickly developed. A 3D walkthrough can be created as fast as the click of a button, and is generally ready within twenty-four hours for the buyers to view. Buyers also find a 3D walkthrough helpful as 3D modeling is designed in such a way, that the buyers are able to move in and out of rooms, and navigate through the 3D walkthrough with ease.

3D visualization, which takes root in 3D modelling, is the easiest way to understand floor plans as well. The best part about 3D modeling and 3D walkthrough is that these can simply be converted to a 3D walkthrough, from a 2D floor plan, with the help of Computer Aided Design (CAD) services. 3D modeling is truly a boon to the profession of architectural design and 3D walkthrough allows these architectural designs to be viewed and sold with no difficulty at all.

3D modeling works out to be very cost competitive and with simulation of the model the errors can be corrected instantly that helps save time and money in the long run!

Impact of Industrial Revolution on Architectural Design https://www.designpresentation.com/blog/impact-of-industrial-revolution-on-architectural-design/ https://www.designpresentation.com/blog/impact-of-industrial-revolution-on-architectural-design/#respond Wed, 10 Oct 2012 12:42:44 +0000 http://www.designpresentation.com/?p=2195 The Industrial Revolution, which happened in the latter half of the 18th century, brought about a number of changes in the architectural scenario all over the world.

The world turned greatly towards Greek and Roman forms of architectural design. It was considered fashionable, and rightly so, to borrow from various types of architectural designs. The Greek designs were what dominated the architectural designs that were taken up, right till the 19th century.

Because the Industrial Revolution also saw advancement in technology and manufacturing facilities, it became easier for architects to design new styles of buildings. New architectural designs were incorporated with ease as builders in one geography adopted architectural designs from elsewhere, which enabled greater diversity and cross-polination of ideas from the time of the Industrial Revolution. It was during the Industrial Revolution that the textile industry also boomed. Because of this development, architectural designs introduced fabrics like velvet and silk. This brought about the concept of interiors being incorporated into the architectural designs, making them interestingly different from all the designs known to exist before this era.

Many who have studied architecture would probably agree that because these architectural designs were drawn by the same contributing factors, they seemed to lack imagination and style. However, these architectural designs were practical, lasting, and only got better with other accompanying advancements.

Advancements in the Industrial Revolution also contributed greatly in the evolution of architectural design as we see them today. At the height of the Industrial Revolution, architecture celebrated both the ornamental and the unadorned and embraced mass production in an almost unbelievable display of goods and resources.

The rise of heavy industry generated a multitude of new building materials such as cast iron, steel, and glass, which enabled architects to design structures that were never before possible.

Apart from architectural designs flourishing with respect to housing and commercial buildings, architecture also saw a boom with respect to other forms of infrastructure such as canals, tunnels, bridges and the likes.

The Industrial Revolution brought about a number of changes in the way architecture was perceived post 18th century. Architectural design took a major turn. Access to better resources, more material, better techniques; all were contributing factors to architecture becoming a full-blown and still flourishing industry today.

Many old architectural drawings dating from the Industrial Revolution have still not been converted to CAD. The process of converting legacy drawings into CAD goes by various names: CAD conversion, CAD vectorization, raster to vector conversion, etc.

Would you like to convert your old paper drawings to CAD?

Many architectural drawings today are as old as the industrial revolution, and are still on the original paper they were printed on. There are several ways to convert them to CAD, including a manual tracing process and the use of auto-vectorization tools. To convert a legacy drawing to CAD free of cost, use our Get-A-Quote form to submit an image of the paper drawing, either a scanned version or simply a photograph. We would be happy to convert one drawing free of cost for you — just use the following discount code: Industrial-Revolution-Free.

How Does BIM Help in the Preparation of Architectural Plans? https://www.designpresentation.com/blog/how-does-bim-help-in-the-preparation-of-architectural-plans/ https://www.designpresentation.com/blog/how-does-bim-help-in-the-preparation-of-architectural-plans/#respond Wed, 10 Oct 2012 06:58:27 +0000 http://www.designpresentation.com/?p=2185 BIM means Building Information Modeling and it is a process wherein the entire lifetime of a structure can be viewed, before it is actually built.
BIM services have been introduced to the architecture industry in order to look after the growing need for professionalism. Right from the stages of conceptualization, to laying down the framework, to the structural development, to the eventual demolition of it, everything about architectural plans can be covered via BIM services, which are used to develop architectural designs of any building structure.


BIM allows architects to stay competitive in the complex market situations, as it allows every architect a bigger platform to perform on and a more innovative set of skills to execute their work. Also, BIM services give the architectural designs an edge over others and gives the architect the ability to predict a more accurate and efficient outcome of the final structure.
BIM services facilitate designing of sustainable and accurate architectural designs. These BIM services are particularly helpful in avoiding errors and saving time. Because of these qualities of the BIM services which are translated into architectural designs, these services are usually preferred extensively for 3D modeling, making home plans and for architectural drafting as well. The advanced technology involved in the execution of BIM services allows architects to collaborate their architectural designs effectively, by way of more reliable coordination. Architectural designs can be made efficiently with the added benefit of higher profits and clients who are satisfied with the outcome.
BIM services enable the process of creating architectural designs to be more efficient and achieve higher levels of quality. BIM services are said to make architectural designs and undertakings precise because the technology incorporates factors such as electrical piping and water and sewage systems of the building as well. Moreover, not only is the external structure well-defined, but the inner structure is also readily available through BIM services. Virtual representations of the architectural designs are also made easier with the help of BIM services, be it conversion of models from 2D to 3D, or the virtual tours wherein the floor plans are exhibited for the client.
BIM services are being adopted by a large number of firms in the architecture industry because of how easy it has made the work of presenting well-executed architectural designs. These services are now getting popular in the industry and are expected to be an integral part of the architectural practices in future. BIM services make work easy and are definitely here to stay.
