Read glTF / GLB for STEP XML output
Transfer glTF / GLB meshes into a STEP XML workflow with the glTF / GLB reader and STEP XML writer. This route carries polygonal geometry in the receiving document; it does not recreate the original CAD surfaces or feature history.
Read the glTF or GLB asset with the OCCT glTF interface. Resolve the geometry and companion resources used by the source scene, then inspect nodes, placements and the appearance information available through the reader.
Choose the STEP XML representation and extension
Transfer the scene meshes through the application document, preserving the selected placements. For a CAD container, write a supported mesh representation rather than claiming recovery of analytic surfaces. Treat unsupported scene properties as separate data to retain or author explicitly.
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 scene scale, axis conventions and repeated objects. Materials, textures and scene behavior may not have an equivalent in the target; compare the required appearance and structure in the receiving application.
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.
