SAT solid input

A known block retained its dimensions, volume and solid count after SAT to STEP conversion and independent read-back. SAB is not enabled. Empty or unreadable geometry is rejected.

Geometry and measurement limits

Converted STEP geometry is independently read back before publishing. Source feature trees are not restored. Properties describe loaded geometry; mass requires your confirmed density.

Download from the workspace

Use the Convert toolbar button to choose STEP and download the result. Preview and download availability depend on readable geometry, file limits and the source version.

Questions about this task

Know the limits.

Which files can I process?

View STEP, IGES, SolidWorks, Siemens NX / UG NX, Inventor, CATIA CATPart/CATProduct, Parasolid X_T, ACIS SAT, JT with readable solids, STL, OBJ, 3MF and static GLB/glTF. ZIP packages retain assembly references. Missing parts show warnings. CATIA CGR/3DXML, X_B, SAB and DWG remain unverified or unavailable.

Are files uploaded?

Yes. Selecting or dropping files uploads and processes them immediately in every tool. Files are processed temporarily on this server. The workspace displays the configured retention time. Delete in the file menu permanently removes your files; closing a view does not.

Do I need an account?

No. Your temporary workspace uses a browser session cookie. There is no account, subscription or permanent file library.

How are properties calculated?

STEP/IGES and converted native CAD use B-Rep geometry; mesh properties are approximate. Incomplete assembly properties cover loaded components only. Mass uses your chosen density.
