Prepare IFC geometry for FBX
The IFC-to-FBX route uses the IFC reader, mesh preparation and the FBX 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.
Prepare mesh geometry for FBX delivery
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.
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
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.
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.
