01

Open your file

Upload a ZIP containing supported CAD models or a glTF scene with its local resources, then inspect the package in one workspace. Select or drop the file to start processing immediately. Files remain private to your guest session and expire after the configured retention period.

02

What is supported

Up to 50 entries and 100 MiB expanded. No encrypted archives, nested ZIPs, symlinks, parent paths or remote resources. Multiple 3D models retain their original coordinates; overlapping volume is not subtracted. A DWG package must contain only one drawing.

03

Read the result responsibly

Display units can be changed without changing source geometry. Confirm source units and material density before using physical properties. A preview is not a manufacturing validation.

A reproducible example

Generated box sample: normalized dimensions 10 × 20 × 30 mm and approximate closed-mesh volume 6,000 mm³. STL/OBJ assume mm; glTF source metres are converted to mm. The ZIP example contains the packaged glTF box.

Repository-generated samples are synthetic test models. Verify your own model's units and geometry before using results.
