Read STEP XML for IGES output
A STEP XML-to-IGES workflow connects the STEP XML reader to the IGES writer. Select the model items and output representation needed by the receiving application.
Read STPX, STPA, STPZ or STPZX with the STEP XML component. The interface supports BRep and mesh representations together with assemblies, names, colors and attributes available in the native STEP data used by the file.
Choose the geometry to deliver through IGES
Inspect whether each selected part contains BRep, mesh or both. A mesh writer can reuse suitable triangles or tessellate CAD surfaces. A precise-geometry writer needs BRep input; storing triangles in a STEP XML file does not reconstruct analytic surfaces.
Transfer supported BRep curves and surfaces with the OCCT IGES writer. Select the geometry and topology representation accepted by the receiving CAD application. This is a precise-source route; a stored visualization mesh does not supply the original analytic geometry.
Check the IGES result
Check nested assembly placements and the relationship between attributes and their model items. Information retained by the reader still needs a compatible mapping in the destination writer.
Reimport the IGES into the destination and check units, open boundaries and surface coverage. Determine whether downstream sewing or healing is required. Keep richer assembly relationships and attributes separately when the selected IGES mapping cannot preserve them.
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.
