3D Model Conversion Quality Checklist
A conversion that opens is not necessarily a conversion that is correct. Run through a short checklist — geometry, scale, color, structure and mesh — before you deliver a converted model to anyone.

Scale & units
Dimensions match the original; units are not off by 1000x.
Color & structure
Color survives if the target supports it; assembly is intact.
What to check, in order
Open the converted model and confirm overall geometry, then verify scale and units, then color/material expectations for the chosen format.
Finally check the assembly structure and that mesh resolution suits the use (web, print or exchange).
Format-specific expectations
Remember STL carries no color; glTF/OBJ can. STEP keeps precise geometry and structure; meshes approximate surfaces.
Judge quality against what the target format is actually capable of.
FAQ
My colors disappeared — is the conversion broken?
Not if you exported to STL, which has no color. Use glTF/OBJ to keep color.
How do I check scale?
Compare a known dimension against the original; unit mismatches often show as 1000x errors.
What about mesh resolution?
Match it to the use case — fine for visualization detail, lighter for performance.
