Private comparison

Start with two models

Choose a trusted baseline and a candidate revision. Import and analysis run in a dedicated browser worker; model data is not uploaded.

Step 01

Choose and interpret source files

STL and OBJ do not carry authoritative units or up-axis metadata. Confirm both explicitly before analysis.

Baseline

Choose a local STL or OBJ file.

Candidate

Choose a local STL or OBJ file.

Analysis method

Sampled surface distance

Approximate, tessellation-dependent comparison at a 0.1 mm distance tolerance. Preconditions and uncertainty remain attached to the result.

Complete both source interpretations

Local boundary: source bytes, normalized geometry, and analysis remain in this browser. No network-backed model service is part of this workflow.
