Read VRML for STEP output
Transfer VRML meshes into a STEP workflow with the VRML reader and STEP 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.
Configure the STEP geometry and document mapping
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 the imported model through the OCCT STEP interface. STEP supports BRep and mesh workflows, so choose the representation supported by the receiving application. Use the document layer when names, colors and assembly relationships are available and need to be transferred.
Check the STEP 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 STEP file in the destination and compare geometry coverage, placements, names and colors. A mesh representation remains polygonal inside STEP. If the next task requires solid modeling, verify that the source and output contain the required BRep geometry.
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.
