Prepare STEP XML geometry for FBX
The STEP XML-to-FBX route uses the STEP XML reader, mesh preparation and the FBX writer. Choose the geometry and representation required by the destination application.
Read STPX, STPA, STPZ or STPZX with the STEP XML component. The interface supports BRep and mesh representations together with assemblies, names, colors and attributes available in the native STEP data used by the file.
Prepare mesh geometry for FBX delivery
Inspect whether each selected part contains BRep, mesh or both. A mesh writer can reuse suitable triangles or tessellate CAD surfaces. A precise-geometry writer needs BRep input; storing triangles in a STEP XML file does not reconstruct analytic 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 nested assembly placements and the relationship between attributes and their model items. Information retained by the reader still needs a compatible mapping in the destination writer.
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.
