OCCT conversion workflows

VRML to STEP XML

Convert VRML to STEP XML. Write STPX, STPA, STPZ or STPZX with supported geometry, names, colors and structure.

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

Read VRML for STEP XML output

Transfer VRML meshes into a STEP XML workflow with the VRML reader and STEP XML writer. This route carries polygonal geometry in the receiving document; it does not recreate the original CAD surfaces or feature history.

Read WRL or VRML geometry through the OCCT VRML interface. Inspect the mesh content and available placements and appearance before constructing the receiving document. Keep referenced resources accessible during import.

Choose the STEP XML representation and extension

Use the imported polygonal geometry for mesh exchange or a mesh-capable CAD container. A scene-format change does not create precise CAD surfaces. Identify any interactive behavior or other source features that fall outside the geometry mapping.

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.

Check the STEP XML result

Compare scale, orientation, geometry coverage and supported appearance. Retain the original scene if its behavior or organization must remain available beyond the geometry exported to the target.

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.

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.

Conversion integration

Build a VRML 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.
