Nut 16K20.040.013 — poor factory scan
- 806×635 px scan from a lathe repair-drawing album
- Model mass 0.507 kg vs 0.5 kg in the title block: the volume is right
- ~4 minutes from scan to STEP
- Tr22×5 LH thread — tap-drill hole plus a note in the report
Send a scan or PDF of a part drawing — get a STEP 3D model, model views side by side with your drawing, a table checking every dimension, and a list of places the scan doesn't allow to read unambiguously.
Open-source drawings: a lathe repair-drawing album and textbook drawings. We never publish client drawings.



Processing runs on the Claude model (Anthropic, USA). If your drawings can't leave your jurisdiction, tell us first and we'll discuss options.
We are responsible for every dimension being checked and every ambiguity being listed. Final acceptance is done by your engineer.
The pilot and test runs are free for now. We quote a price after the test, once your volumes and part types are clear.
Ideally different ones: a simple part, a complex housing, a poor scan. You get models and verification reports — and decide whether it helps.
