Read STEP for VRML output
A STEP-to-VRML workflow connects the STEP reader to the VRML writer. Select the model items and output representation needed by the receiving application.
Read STP or STEP files with the OCCT STEP reader. STEP supports precise BRep and mesh representations, along with assembly structure and supported attributes through the XDE document workflow.
Prepare a VRML visualization derivative
Inspect the selected parts before choosing their output representation. Preserve BRep for a precise-geometry writer; reuse suitable source meshes or tessellate the CAD surfaces for a mesh destination. Keep assembly placements associated with their parts.
Write the selected mesh representation through the OCCT VRML interface for a consumer that expects WRL or VRML. Map the geometry, placements and supported appearance information required by that viewer. Keep precise CAD topology and unsupported attributes in the engineering source.
Check the VRML result
Check the STEP representation, unit scale, names, colors and required attributes. A source file containing tessellated data does not necessarily contain the analytic geometry needed for subsequent solid modeling.
Open the output in the receiving VRML application and check scale, orientation and part positions. Verify the actual appearance mapping and any resource references. Compare the tessellation against the viewing task rather than judging fidelity from successful file loading alone.
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.
