Prepare JT geometry for FBX
The JT-to-FBX route uses the JT reader, mesh preparation and the FBX writer. Choose the geometry and representation required by the destination application.
JT can contain stored visualization meshes, embedded Parasolid BRep, or both. Select the representation needed for the destination before reading the assembly. The Parasolid interface imports precise geometry only when the JT file contains Parasolid BRep data.
Prepare mesh geometry for FBX delivery
For a mesh route, select a suitable stored level of detail or tessellate the imported Parasolid BRep with the required deflection. For a precise-geometry route, use the embedded BRep; a mesh-only JT file cannot supply the original CAD surfaces.
Write the selected mesh geometry with the commercial FBX interface. Prepare the supported scene and placement mapping required by the receiving application. Check appearance and other attributes individually rather than assuming all source properties have an FBX writer mapping.
Validate the converted model
Check part placements and repeated instances as well as names, colors and transparency. A stored coarse level of detail cannot regain surface detail merely by changing file format.
Reopen the FBX in the destination and compare scale, orientation, geometry coverage and placements. Verify the actual version and property mapping needed by that application. Retain the engineering source for information that the scene derivative cannot carry.
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.
