Read IGES for STEP XML output
A IGES-to-STEP XML workflow connects the IGES reader to the STEP XML writer. Select the model items and output representation needed by the receiving application.
Read IGS or IGES geometry with the OCCT IGES interface. Inspect the transferred curves, surfaces and topology before conversion: an IGES model may contain disconnected surfaces or wire geometry rather than a closed solid.
Choose the STEP XML representation and extension
For mesh output, tessellate the imported faces and inspect boundaries between adjacent surfaces. Curves alone do not define a surface mesh. For BRep output, determine whether sewing or shape healing is needed before writing the translated geometry.
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
Check units, surface coverage, open boundaries and tolerances. A successful translation does not establish watertightness or restore product structure that the source IGES file did not contain.
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.
