Prepare IFC geometry for JT
The IFC-to-JT route uses the IFC reader, mesh preparation and the JT writer. Choose the geometry and representation required by the destination application.
Read the IFC model through the IFC interface and select the building elements needed by the recipient. Inspect the imported geometry and element placements before preparing a scene or polygonal derivative.
Build a JT visualization model
Use existing meshes or tessellate supported imported BRep surfaces. Keep object placement consistent across the selected building model, and choose mesh detail suitable for the scale and use of the output.
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 converted model
Compare geometry coverage, unit scale and positioning. BIM relationships, classifications and property sets require explicit retention checks; a polygonal file is not a replacement for the complete IFC model.
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 repeated jobs, retain the source, preparation settings and representative output checks. Discuss this conversion with the input files, destination application and required geometry and attributes.
