OCCT conversion workflows

Parasolid to IGES

Convert Parasolid to IGES. Translate source BRep curves and surfaces with the OCCT IGES writer and check geometry coverage.

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

Read Parasolid for IGES conversion

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

Choose the geometry to deliver through IGES

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.

Transfer supported BRep curves and surfaces with the OCCT IGES writer. Select the geometry and topology representation accepted by the receiving CAD application. This is a precise-source route; a stored visualization mesh does not supply the original analytic geometry.

Validate the IGES 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.

Reimport the IGES into the destination and check units, open boundaries and surface coverage. Determine whether downstream sewing or healing is required. Keep richer assembly relationships and attributes separately when the selected IGES mapping cannot preserve them.

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 IGES workflow

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