Read OBJ for JT conversion
A OBJ-to-JT workflow combines the OBJ reader with the JT writer. Use it when the receiving application needs JT data from an existing OBJ model.
Read Wavefront OBJ polygonal geometry through the OCCT workflow. Check the associated material resources and object grouping where these are used by the source asset. Keep the geometry and its required companion files together.
Build a JT visualization model
This is a mesh-to-mesh route. Preserve the available surface triangles, apply the required placements and map only the attributes supported by both the reader and writer. It does not reconstruct a CAD feature history or analytic BRep.
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
Check object grouping, orientation and units with the receiving application. Normals and material references need explicit validation, particularly when the source uses external resources.
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.
