OCCT conversion workflows

Parasolid to OCCT BRep

Convert Parasolid to OCCT BRep. Read precise source geometry and store native OCCT shapes for CAD processing and analysis.

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

Read Parasolid for OCCT BRep conversion

A Parasolid-to-OCCT BRep workflow combines the Parasolid reader with the OCCT BRep writer. Use it when the receiving application needs OCCT BRep 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.

Store imported geometry as native OCCT shapes

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.

Write the imported precise shapes using native OCCT BRep storage. This route is useful for retaining translated geometry for subsequent OCCT modeling and analysis. It requires BRep source geometry and does not recover analytic surfaces from a mesh-only representation.

Validate the OCCT BRep 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.

Read the BRep file back with the intended OCCT delivery and compare shape types, tolerances and geometry coverage. A standalone BRep file does not carry the complete XDE assembly and attribute document; choose XCAF storage when that document-level information must be preserved.

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 OCCT BRep workflow

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