OCCT conversion workflows

XPDMXML to STL

Convert XPDMXML to STL through a mesh workflow. Prepare geometry, map supported data and validate the result in the receiving application.

Build this conversion into your application with OCCT readers, writers and the commercial components identified below.

Prepare XPDMXML geometry for STL

The XPDMXML-to-STL route uses the XPDMXML reader, mesh preparation and the STL 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.

Write the selected surfaces as STL triangles

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.

Prepare triangulation for the selected geometry and write it with the OCCT STL interface. Set mesh detail for the destination task. STL does not retain the full assembly tree, names, colors or CAD metadata; keep the source model when those relationships matter.

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 unit scale, bounds, face orientation and connectivity in the receiving application. Include small features and curved regions in the comparison. Producing an STL file does not itself validate printability, watertightness or suitability for material removal.

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.

Conversion integration

Build a XPDMXML to STL workflow

Share the source and receiving applications, representative files, required attributes and throughput. We can scope SDK evaluation or an integrated conversion service.
