Read Blender BLEND for XCAF output
Transfer Blender BLEND meshes into a XCAF workflow with the Blender BLEND reader and XCAF writer. This route carries polygonal geometry in the receiving document; it does not recreate the original CAD surfaces or feature history.
Read the supported mesh and scene content from the Blender file. Blender authoring data such as procedural operations or editing history must not be treated as exported CAD geometry.
Build and store an XCAF document
The Assimp integration provides mesh geometry, colors, materials and scene structure for its supported inputs. Pass that data to a separate OCCT or commercial writer. For STEP, STEP XML or DXF output, use the mesh-capable representation; this does not reconstruct BRep surfaces from polygons.
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.
Check the XCAF result
Check which objects and their visible geometry are present in the imported result. Keep the original Blender project for authoring data that the exchange route does not retain.
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.
Discuss this conversion with the producing and receiving applications, representative files and required geometry and attributes. Compare the reader/writer catalog when a different representation is needed.
