Prepare XPDMXML geometry for XCAF
The XPDMXML-to-XCAF route uses the XPDMXML reader, mesh preparation and the XCAF writer. Choose the geometry and representation required by the destination application.
Read the XPDMXML product data through its interface and resolve the geometry required by the selected model items. Keep referenced model resources available; product structure without its geometric content cannot supply an export mesh.
Build and store an XCAF document
Prepare meshes for the resolved shapes, keeping part occurrences and their placements consistent. Use suitable source meshes directly or tessellate BRep surfaces at the required detail.
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
Check geometry completeness and reference resolution before judging the output. Product identifiers, revisions and other management data need an explicit destination mapping or a separate retained record.
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.
