PartProof Verified CAD Automation
Build CAD.
Prove it.
PartProof turns specs, drawings, and imported geometry into editable CAD features—automatically. Every feature is validated and every result is provable.

How it works
From engineering intent to verified CAD evidence.
The current beta focuses on proving the core workflow clearly: generate editable CAD features, validate the output, and keep a trace your team can review.
Generate editable features
PartProof converts recognized intent into CAD features your team can inspect and modify.
Validate readback
Dimensions, tolerances, and feature results are checked against engineering rules.
Keep proof
Each automation run leaves a traceable record of what was created, checked, and reviewed.
