A final design review can prevent expensive manufacturing mistakes. Use this mechanical design review checklist before releasing a CAD model, fabrication drawing or production package.
CAD Model Checks
- Confirm the correct part number.
- Verify overall dimensions.
- Check feature locations.
- Remove unnecessary geometry.
- Confirm material assignment.
- Check model units.
- Review configurations or variants.
Engineering Drawing Checks
- Confirm projection method.
- Check front, top and side views.
- Verify dimensions against the CAD model.
- Check tolerances.
- Review GD&T callouts.
- Check section views and details.
- Verify centerlines and hidden lines.
- Review surface-finish requirements.
- Check welding or fabrication notes where applicable.
Manufacturing Checks
- Can the part be manufactured with the intended process?
- Are standard tools and materials used where practical?
- Are tight tolerances functionally justified?
- Can inspection equipment access critical features?
- Have sharp edges and deburring requirements been considered?
Release Checks
- Confirm revision number.
- Verify title block information.
- Check BOM and quantities.
- Ensure the released PDF and CAD files match.
Why a Checklist Helps
Design review is not about finding fault with the designer. It is a structured way to verify that the product intent has been communicated clearly to manufacturing, procurement, inspection and assembly teams.
Use this CAD drawing checklist as a starting point and customize it for your company’s products, standards and manufacturing processes.
