Read OCCT BRep for JT conversion
A OCCT BRep-to-JT workflow combines the OCCT BRep reader with the JT writer. Use it when the receiving application needs JT data from an existing OCCT BRep model.
Read native OCCT BRep shapes from BREP or SHAPE files. This provides geometry and topology for modeling or tessellation. A standalone shape file is not an XDE document and should not be assumed to contain assembly names, colors or materials.
Build a JT visualization model
Use the imported shapes directly for a precise CAD writer, or generate surface triangulation for a mesh writer. If the input contains open shells, faces or wires, select the geometry appropriate to the target instead of assuming every shape is a solid.
Use the OCAF-to-JT converter for supported hierarchy, names, colors and mesh representations. Configure tessellation and any required levels of detail around the viewing task. This output route creates a visualization representation; it does not promise Parasolid BRep export inside JT.
Validate the JT result
If application-owned labels, placements or appearance must accompany the shape, supply them explicitly in the document passed to the writer. Keep this enrichment distinct from information read from the BRep file.
Select a JT version accepted by the recipient and check part positions, geometry coverage and appearance there. Compare both the full assembly and selected parts. If later processing requires precise CAD surfaces, retain the source BRep alongside the visualization derivative.
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.
