OCCT conversion workflows

DXF to FBX

Convert DXF to FBX through a mesh workflow. Prepare geometry, map supported data and validate the result in the receiving application.

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

Prepare DXF geometry for FBX

The DXF-to-FBX route uses the DXF reader, mesh preparation and the FBX writer. Choose the geometry and representation required by the destination application.

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 mesh geometry for FBX delivery

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 the selected mesh geometry with the commercial FBX interface. Prepare the supported scene and placement mapping required by the receiving application. Check appearance and other attributes individually rather than assuming all source properties have an FBX writer mapping.

Validate the converted model

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 FBX in the destination and compare scale, orientation, geometry coverage and placements. Verify the actual version and property mapping needed by that application. Retain the engineering source for information that the scene derivative cannot carry.

For repeated jobs, retain the source, preparation settings and representative output checks. Discuss this conversion with the input files, destination application and required geometry and attributes.

Conversion integration

Build a DXF to FBX workflow

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