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.
Use models with known units and coordinate systems. VoxelSpy preserves source meaning instead of silently shifting or resizing either model.
Review the import
Confirm units, coordinate transforms, unsupported content, and approximation warnings before interpreting a difference. Corrections are deliberate inputs and remain visible in the result.
Inspect before sharing
Move from the overview to ranked regions and sections. Export is a separate action; selecting local files does not upload them.
