Read VRML for STL output
A VRML-to-STL workflow connects the VRML reader to the STL writer. Select the model items and output representation needed by the receiving application.
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.
Write the selected surfaces as STL triangles
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.
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.
Check the STL 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.
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.
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.
