Prepare STEP geometry for FBX
The STEP-to-FBX route uses the STEP reader, mesh preparation and the FBX writer. Choose the geometry and representation required by the destination application.
Read STP or STEP files with the OCCT STEP reader. STEP supports precise BRep and mesh representations, along with assembly structure and supported attributes through the XDE document workflow.
Prepare mesh geometry for FBX delivery
Inspect the selected parts before choosing their output representation. Preserve BRep for a precise-geometry writer; reuse suitable source meshes or tessellate the CAD surfaces for a mesh destination. Keep assembly placements associated with their parts.
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 the STEP representation, unit scale, names, colors and required attributes. A source file containing tessellated data does not necessarily contain the analytic geometry needed for subsequent solid modeling.
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.
