Read AC3D for STEP XML output
Transfer AC3D meshes into a STEP XML workflow with the AC3D 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 AC3D .ac mesh asset through the Assimp integration. Inspect object structure, polygon geometry and the material data returned by the reader.
Choose the STEP XML representation and extension
The Assimp integration provides mesh geometry, colors, materials and scene structure for its supported inputs. Pass that data to a separate OCCT or commercial writer. For STEP, STEP XML or DXF output, use the mesh-capable representation; this does not reconstruct BRep surfaces from polygons.
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
Compare grouped objects, placements and supported colors or materials. Keep source resources available and verify the appearance expected by the recipient.
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.
