Confirm file and revision
Match part number and revision across 2D and 3D, identify the quoted configuration and remove reference components outside scope.

CAD file preflight checklist before a machining RFQ
A short review reduces revision mistakes, missing units and avoidable clarification cycles.
Check units, scale and geometry
Compare overall size with a known dimension. Check DXF scale and profiles, STEP bodies and faces, and explicitly state STL units.
Compare 2D and 3D
Cross-check holes, threads, slots, radii, wall thickness and datums. Identify the governing document if they differ.
Final checklist
A one-minute check prevents repeated clarification.
- Matching revision
- Explicit units
- Complete DXF profiles
- Correct STEP bodies
- Defined tolerances and finishes
- Quantity and required date
- Governing document identified
FAQ
Frequently asked questions
Can the viewer detect every error?
No. It supports preliminary viewing; engineering and manufacturing review is still required.
What if 2D and 3D conflict?
Flag the discrepancy and release a consistent governing revision.
