Prepare FBX geometry for XCAF
The FBX-to-XCAF route uses the FBX reader, mesh preparation and the XCAF writer. Choose the geometry and representation required by the destination application.
Read the FBX input with the commercial interface and select the model geometry needed by the receiving application. Inspect the available scene organization and placements before preparing output meshes.
Build and store an XCAF document
Reuse imported mesh geometry or tessellate imported surfaces where needed. Select a static model state for destinations that do not carry scene behavior. Do not infer full animation or material compatibility from the fact that both files are scene formats.
Place the imported geometry in an XCAF document and map the supported names, colors and structure to its labels. Use the native OCCT document storage appropriate to the selected XBF or XML delivery. Mesh data can remain mesh in the document; creating labels does not generate analytic CAD surfaces.
Validate the converted model
Compare geometry coverage, scale, orientation and part placements. Verify each required appearance or structure property through the complete reader-to-writer route.
Reopen the document in the intended OCCT application and verify geometry, occurrence placements and mapped attributes. Keep application-specific additions distinct from source properties. XCAF storage is useful for continuing an OCCT workflow, but the recipient must support the chosen document format.
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.
