Keep each file accountable
Every selected STEP file gets its own processing status. A failed file stays in the list with a reason instead of silently disappearing from the report.

Batch STEP Properties: Export CAD Measurements to CSV
Process a batch of STEP files and export real dimensions, area, volume and density-based mass as CSV.
No account required
Temporary workspaceCAD processingBefore you use the result
Know what you are looking at.
Use one row per source to keep a mixed batch understandable. Record units, calculation scope and failures alongside the values rather than silently omitting difficult files.
Use consistent units and density
Dimensions, area and valid solid volume are normalized to millimetres. The density you choose is applied consistently when estimating mass; confirm that it is suitable for the parts in your batch.
Take the properties with you
Export a CSV containing file names, status, dimensions, surface area, volume, density, mass, source units and warnings. This release does not export converted models or ZIP packages.
A reproducible example
Generated STEP block: 20 × 30 × 40 mm, surface area 5,200 mm² and volume 24,000 mm³. At density 2.7 g/cm³ the calculated mass is 64.8 g. These values describe the synthetic block, not the default bearing sample.
Repository-generated samples are synthetic test models. Verify your own model's units and geometry before using results.
Questions about this task
Know the limits.
Does each file get its own CSV row?
Each temporary task receives one row with units, status and warnings. A ZIP is one aggregate task, not one row per member.
Which density is exported?
The current batch density is applied to available volumes. Failed or volume-less models keep empty mass values and an explanatory status.
Are my files uploaded?
Selecting a file starts temporary server processing. Access is limited to your guest session. The entry shows configured retention and files can be deleted earlier.
