OCCT conversion workflows

Parasolid to OBJ

Convert Parasolid to OBJ. Prepare polygonal geometry, grouping and supported appearance for Wavefront OBJ output.

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

Read Parasolid for OBJ conversion

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

Prepare polygonal geometry for OBJ

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 selected surface mesh with the OBJ interface. Establish whether the consumer needs per-part grouping, normals or supported appearance information, and preserve any associated material resources produced by the writer. A polygon file is not a replacement for the full CAD document.

Validate the OBJ 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.

Check the OBJ in the receiving graphics or geometry tool, including scale, face orientation, grouping and companion-file references. Where a flat mesh cannot retain the original assembly relationships, keep that engineering information separately.

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 OBJ workflow

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