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 source files

Select two supported files to compare immediately using common millimetre and right-handed Z-up defaults. If a source uses a different frame, adjust its Expert settings first.

BaselineChoose a modelSTL or OBJ, up to 32 MiB

Expert settings

Change these only when the source uses a different unit or up-axis. The selected values are recorded with the comparison.

Source unitSource up-axis

Choose a local STL or OBJ file.

CandidateChoose a modelSTL or OBJ, up to 32 MiB

Expert settings

Change these only when the source uses a different unit or up-axis. The selected values are recorded with the comparison.

Analysis method

Sampled surface distance

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

Analysis RAM allowance256 MiBThis is a ceiling, not preallocated memory. Raising it also gives the local worker more compute time; large settings may slow or destabilize this tab.

Choose both source files

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