Getting started
Prepare two models for a private, local comparison.
Choose a baseline and candidate
The baseline is the model you trust. The candidate is the revision you want to inspect. Choose both from your device; normal comparison keeps their geometry in your browser.
This release accepts STL, OBJ, glTF, GLB, and 3MF. STL and OBJ import starts with common millimetre and right-handed Z-up settings, since neither format declares a source frame; glTF/GLB and 3MF resolve their frame from the file itself instead. If a source needs a different interpretation than what it starts from or declares, change its Expert settings before comparison; the selected interpretation remains attached to the result.
Review the import
Review the interpreted units, coordinate transforms, unsupported content, and approximation warnings before relying on a difference. Corrections are deliberate inputs and remain visible in the result.
Inspect before sharing
Move from the overview to ranked regions and sections. Exporting a report or saving a session are both separate, explicit actions; selecting local files does not upload them.
