OCCT conversion workflows

OCCT BRep to STEP XML

Convert OCCT BRep to STEP XML. Write STPX, STPA, STPZ or STPZX with the supported geometry, assembly and attribute mapping.

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

Read OCCT BRep for STEP XML conversion

A OCCT BRep-to-STEP XML workflow combines the OCCT BRep reader with the STEP XML writer. Use it when the receiving application needs STEP XML data from an existing OCCT BRep model.

Read native OCCT BRep shapes from BREP or SHAPE files. This provides geometry and topology for modeling or tessellation. A standalone shape file is not an XDE document and should not be assumed to contain assembly names, colors or materials.

Choose the STEP XML representation and extension

Use the imported shapes directly for a precise CAD writer, or generate surface triangulation for a mesh writer. If the input contains open shells, faces or wires, select the geometry appropriate to the target instead of assuming every shape is a solid.

Write STPX, STPA, STPZ or STPZX with the STEP XML component. It supports BRep and mesh data, assemblies, names, colors and STEP attributes. Transfer only the source information available through the complete route; the target can carry mesh without turning it into analytic geometry.

Validate the STEP XML result

If application-owned labels, placements or appearance must accompany the shape, supply them explicitly in the document passed to the writer. Keep this enrichment distinct from information read from the BRep file.

Reopen the selected STEP XML variant with the intended consumer. Check geometry representation, placements, names and colors, and explicitly verify any required attributes. Use the agreed extension and application version for repeatable interchange.

For a production pipeline, keep a representative source file and its expected geometry and attributes with the conversion settings. Discuss conversion integration with the source and destination applications, or compare the supported format interfaces.

Conversion integration

Build a OCCT BRep to STEP XML workflow

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