Manufacturing drawings are also known as production drawings or working drawings.

These drawings are split into two main categories:

Part/component drawings

These drawings detail the part or parts required in the manufacturing process along with information on the finishing processes.

The following information should be included:

  • Material specification
  • Dimensions and tolerances
  • Surface finish type

Assembly drawings

Assembly drawings are usually split into three categories; top level assembly, sub-assembly and individual parts.

Assembly drawings are essentially created to provide detailed instructions for the main assembly of the full product and are therefore very comprehensive.

Assembly drawings should include the following:

  • All parts and components to be manufactured
  • Specific part numbers or codes relevant to each component
  • Fixings, such as nuts, bolts, washers, etc
  • Bill of Materials (BOM) showing a detailed list of parts and components
  • Various views can be utilised to demonstrate how the final product is assembled, including: Top view, side view, detailed view and section view and exploded views
  • Additional information can be included if necessary, i.e. mass properties, weights and assembly instructions

HDL CAD Solutions offer a full manufacturing drawing package as detailed above. In order to create the drawings, we require the following information:

  • Paper drawings or sketches
  • Concept drawings, parts or images
  • Existing CAD drawings, 2D or 3D models
