OCCT conversion workflows

Parasolid to ACIS SAT / SAB

Convert Parasolid to ACIS SAT / SAB. Translate source BRep to SAT or SAB with the commercial ACIS writer and target-version checks.

Build this conversion into your application with OCCT readers, writers and the commercial components identified below.

Read Parasolid for ACIS SAT / SAB conversion

A Parasolid-to-ACIS SAT / SAB workflow combines the Parasolid reader with the ACIS SAT / SAB writer. Use it when the receiving application needs ACIS SAT / SAB data from an existing Parasolid model.

Read Parasolid X_T or X_B files through the commercial Parasolid interface into OCCT BRep shapes. Use the XDE import layer when supported names and colors must remain associated with the model items.

Translate precise geometry into ACIS

Keep the imported BRep for precise CAD output. For polygonal output, generate a surface mesh with tolerances selected for the receiving application. Check any healing settings against the geometry used in production.

Use the ACIS writer for supported BRep geometry and select SAT or SAB for the receiving application. The published component description lists output through ACIS version 7; confirm the delivery and recipient version. A mesh-only input needs another route rather than an implied reconstruction of smooth CAD surfaces.

Validate the ACIS SAT / SAB result

This route starts from a Parasolid export, not an arbitrary native file from a Parasolid-based application. Parasolid writing is not provided by the documented import component.

Reopen the file in the recipient and check topology, surface coverage, units and supported attributes. Include translated curved surfaces and multi-body models in the comparison. Reading a file successfully is only the first check when the next task is a modeling operation.

For a production pipeline, keep a representative source file and its expected geometry and attributes with the conversion settings. Discuss conversion integration with the source and destination applications, or compare the supported format interfaces.

Conversion integration

Build a Parasolid to ACIS SAT / SAB workflow

Share the source and receiving applications, representative files, required attributes and throughput. We can scope SDK evaluation or an integrated conversion service.
