OCCT conversion workflows

DXF to USD / USDZ

Convert DXF to USD / USDZ. Prepare meshes, assembly placements and supported appearance for USD, USDZ or USDA scenes.

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

Read DXF for USD / USDZ conversion

A DXF-to-USD / USDZ workflow combines the DXF reader with the USD / USDZ writer. Use it when the receiving application needs USD / USDZ data from an existing DXF model.

Read DXF entities through the DXF component and identify curves, embedded BRep bodies and mesh data. DXF import and export support mesh workflows as well as BRep, but the actual source entities determine which path is available.

Prepare a USD scene from the imported geometry

Use existing mesh data or tessellate imported BRep faces for a polygonal target. A curve-only drawing requires surface construction before a surface-mesh export; this is a modeling step that cannot be inferred from the DXF extension.

Write USD, USDZ or USDA through the USD component. Map supported names, part placements and appearance into the scene. The component supports meshes, primitives, metadata, materials and animations, but this conversion can preserve only data actually available from the source or explicitly authored by the application.

Validate the USD / USDZ result

Check drawing units, entity coverage and placements. Establish how layers, names and supported colors map to the receiving document instead of assuming that CAD drawing organization is identical to a scene hierarchy.

Reopen the scene in the receiving USD application. Compare axis conventions, unit scale, hierarchy, repeated parts and material assignments. Review external resources or packaging for the chosen output variant; the retained CAD source remains the reference for precise modeling.

For a production pipeline, keep a representative source file and its expected geometry and attributes with the conversion settings. Discuss conversion integration with the source and destination applications, or compare the supported format interfaces.

Conversion integration

Build a DXF to USD / USDZ workflow

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