01

Open your file

View OBJ triangle geometry and approximate dimensions, area and closed-mesh volume without an account. 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

OBJ coordinates assume millimetres. Geometry is displayed without MTL libraries or textures. B-Rep edge measurement and solid differences are unavailable.

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.
