Context
Review cycles slow down when files are incomplete or inconsistent. The right package can cut days off the loop.
A fast DFM review depends on the file set: PDF drawings for intent, STEP or IGES for geometry, and clear revision tags to avoid rework.
The Trap
The trap is sending CAD without the drawing, or a drawing without the tolerance map. Review teams need both.
The Geppetto Take
We shorten reviews by eliminating ambiguity. A clean CAD + PDF set with tolerance notes and finish specs prevents back-and-forth.
Evidence / Data
- Missing tolerances or finish notes are the most common review blockers.
- Clear revision control reduces rework and confusion.
Control Actions
- Provide CAD (STEP) and PDF drawing.
- Include a tolerance map and datum scheme.
- Define material, finish, and quantity.
- Use consistent revision naming.
Checklist
- CAD + PDF in the same revision.
- Tolerance map included.
- Finish and material specified.
- Contact for clarifications assigned.
What to Send
Send the CAD, PDF, and any inspection requirements or special notes.
FAQ
Can we review from CAD only?
We can, but drawing notes often contain critical tolerances.
What file format is best?
STEP + PDF drawing is the fastest path.
Do you need GD&T details?
Yes, because it drives process and inspection.
