Read glTF / GLB for STEP output
Transfer glTF / GLB meshes into a STEP workflow with the glTF / GLB reader and STEP 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.
Configure the STEP geometry and document mapping
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 the imported model through the OCCT STEP interface. STEP supports BRep and mesh workflows, so choose the representation supported by the receiving application. Use the document layer when names, colors and assembly relationships are available and need to be transferred.
Check the STEP 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 STEP file in the destination and compare geometry coverage, placements, names and colors. A mesh representation remains polygonal inside STEP. If the next task requires solid modeling, verify that the source and output contain the required BRep geometry.
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.
