Prepare XPDMXML geometry for OBJ
The XPDMXML-to-OBJ route uses the XPDMXML reader, mesh preparation and the OBJ 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.
Prepare polygonal geometry for OBJ
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.
Write the selected surface mesh with the OBJ interface. Establish whether the consumer needs per-part grouping, normals or supported appearance information, and preserve any associated material resources produced by the writer. A polygon file is not a replacement for the full CAD document.
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.
Check the OBJ in the receiving graphics or geometry tool, including scale, face orientation, grouping and companion-file references. Where a flat mesh cannot retain the original assembly relationships, keep that engineering information separately.
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.
