Assembly drawings show how components of a system, kit or building fit together. They may include, orthogonal plans, sections and elevations, or three-dimensional views. They show the assembled components, or an exploded view showing the relationship between the components and how they fit together. Also, they may include instructions, lists of the component parts, reference numbers, references to detail drawings or shop drawings, and specification information.
Main Types
- General Assembly: This type of drawing shows the complete layout of a complete machine or structure with key dimensions and a Bill of Materials (BOM).
- Detailed / Working Assembly: You may need detailed drawings with instructions and precise tolerances for items like gearboxes or bearing housings.
- Subassembly Drawing: This type of drawing focuses on a subset of parts, i.e. a subassembly that gets built first before integration into a overall machine or structure.
- Exploded Assembly: An exploded drawing shows parts pulled apart along a straight line to make manual assembly or maintenance easier to understand.
Skills Required to Produce Assembly Drawings
Preparing assembly drawings requires specialized CAD drafting skills, which are not always easy to find. That’s where Design Presentation comes in. Design Presentation is a US-based leading provider of Assembly Drawings. We serve thousands of engineers, architects and construction firms around the world
The final drawings that we prepare include all details for fabricating the assembly. For example, we will include the number of assemblies, BOM and references.
Clients rely on us for a number of reasons:
- To redline existing components to reflect design changes and verify the functionality of the final assembly</li
- To reverse engineer and produce component drawings
- To undertake 3D engineering in a program such as SolidWorks
- To archive manufacturing data
- To convert format from one CAD program to another (to conform with a manufacturer’s requirements)
