OCCT conversion workflows

Parasolid to XCAF

Convert Parasolid to XCAF for OCCT applications. Store imported geometry with supported names, colors and document structure.

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

Read Parasolid for XCAF output

A Parasolid-to-XCAF workflow connects the Parasolid reader to the XCAF writer. Select the model items and output representation needed by the receiving application.

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.

Build and store an XCAF document

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.

Place the imported geometry in an XCAF document and map the supported names, colors and structure to its labels. Use the native OCCT document storage appropriate to the selected XBF or XML delivery. Mesh data can remain mesh in the document; creating labels does not generate analytic CAD surfaces.

Check the XCAF 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 document in the intended OCCT application and verify geometry, occurrence placements and mapped attributes. Keep application-specific additions distinct from source properties. XCAF storage is useful for continuing an OCCT workflow, but the recipient must support the chosen document format.

Discuss this conversion with the producing and receiving applications, representative files and required geometry and attributes. Compare the reader/writer catalog when a different representation is needed.

Conversion integration

Build a Parasolid to XCAF workflow

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