Native CAD vs STEP?
STEP is enough for quote; native helps some DFM checks.

What to Upload for an Accurate Injection Molding Quote
Instant quotes read geometry from STEP or IGES; missing draft or wall thickness shows up in DFM feedback.

Files drive quote assumptions
STEP plus drawing revision beats a screenshot of a part.
Instant quotes read geometry from STEP or IGES; missing draft or wall thickness shows up in DFM feedback.
A 2D PDF with revision block and critical dimensions reduces back-and-forth on tolerances.
Quantity and finish notes belong in the same upload session as CAD.

Common gaps
Weak callouts widen assumptions; specific grades tighten quotes.
| Field | Too vague | Better |
|---|---|---|
| File | STL only | STEP preferred for molding DFM |
| Rev | Unmarked CAD | Rev letter on both 2D and 3D |
| Qty | Missing | First order plus annual estimate |
