OCCT conversion workflows

DXF to glTF / GLB

Convert DXF bodies and meshes to glTF or GLB. Prepare scene geometry, supported names, colors and structure for browser visualization.

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

Bring DXF models into a web scene

The DXF reader supports BRep bodies and mesh data alongside drawing curves. A DXF-to-glTF pipeline reads the supported entities, prepares surface meshes where required and exports a glTF or GLB scene.

BRep bodies can be tessellated, while existing mesh entities can follow the mesh conversion route. For a source containing only drawing curves, define the surface-building or separate line-visualization workflow needed by the application; do not silently treat it as a complete 3D surface model.

Preserve the useful document context

Use XDE when names, colors and assembly information need to remain associated with the imported geometry. Map the selected items and their placements to scene nodes, then configure the writer for the receiving viewer.

Where tessellation is required, select deflection and element sizes for the expected viewing distance. Express Mesh provides CAD meshing controls. Existing coarse meshes need a suitable source or a separate processing step if the visualization requires more detail.

Check delivery in the browser

Compare scene hierarchy, object placement, scale and supported appearance in the target application. DXF drawing annotations and layout do not automatically become an equivalent interactive scene presentation.

For glTF with associated resources, distribute the complete asset set. Light Web Viewer can provide navigation, selection and inspection in the host application. For a triangle-only destination, use DXF to STL; for a CAD exchange document, see DXF to STEP.

Conversion integration

Build a DXF to glTF / GLB workflow

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