Read Parasolid for PLY conversion
A Parasolid-to-PLY workflow combines the Parasolid reader with the PLY writer. Use it when the receiving application needs PLY 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.
Select the polygon data required by the PLY consumer
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 a polygonal derivative with the OCCT PLY interface. Agree on the mesh and property fields needed by the consumer: the PLY extension alone does not guarantee compatible color or other per-element property handling. Keep assembly and CAD metadata separately when it has no destination mapping.
Validate the PLY 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 PLY in the downstream processing tool and compare units, bounds, surface coverage and the expected properties. Native PLY support in the catalog is write-only; this route does not imply a native PLY reader for the reverse direction.
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.
