Read XCAF for JT output
A XCAF-to-JT workflow connects the XCAF reader to the JT writer. Select the model items and output representation needed by the receiving application.
Read the native XCAF document with the OCCT storage interface matching its file type. Inspect document shapes, assembly occurrences and attributes before selecting the part of the document to exchange.
Build a JT visualization model
Choose BRep or mesh geometry according to the actual shapes in the document and the destination. Resolve assembly placements and map supported names and colors. Native document storage can contain application information that another CAD or scene format does not represent.
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.
Check the JT result
Check occurrence placement separately from shared part geometry. Validate transferred labels and attributes, and keep the source XCAF document when application-specific data or edit structure needs to be retained.
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.
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.
