OCCT conversion workflows

glTF / GLB to DXF

Convert glTF / GLB meshes to DXF. Write supported mesh entities, map placements and check geometry in the receiving CAD application.

Build this conversion into your application with OCCT readers, writers and the commercial components identified below.

Read glTF / GLB for DXF output

Transfer glTF / GLB meshes into a DXF workflow with the glTF / GLB reader and DXF 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.

Select DXF entities for the transferred model

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.

Configure the DXF writer for the receiving application and the selected geometry. The interface supports BRep and mesh export; use an entity representation the consumer accepts. Decide how model names, colors and drawing organization should map rather than assuming every CAD application interprets them identically.

Check the DXF 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 DXF in the target application and inspect entity coverage, units and placements. Verify that the receiver handles the written bodies or meshes as intended. A surface-mesh export is not an automatically generated 2D manufacturing drawing.

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.

Conversion integration

Build a glTF / GLB to DXF workflow

Share the source and receiving applications, representative files, required attributes and throughput. We can scope SDK evaluation or an integrated conversion service.
