Private by design

Your selected files stay in this browser. Parsing runs locally in a separate worker. This viewer sends no model files to a server.

Know the limits

Solid and surface STEP geometry is supported. Wire-only, corrupt or unsupported files may contain no renderable faces. Large assemblies depend on device memory; import can be cancelled. This is a viewing aid, not a CAD editor.

A known-size sample

The sample is a real STEP solid: a 60 × 40 × 12 mm block. Download the sample to test it yourself.
