OCCT conversion workflows

DXF to STEP XML

Convert DXF to STEP XML. Write STPX, STPA, STPZ or STPZX with supported geometry, names, colors and structure.

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

Read DXF for STEP XML output

A DXF-to-STEP XML workflow connects the DXF reader to the STEP XML writer. Select the model items and output representation needed by the receiving 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.

Choose the STEP XML representation and extension

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 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

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 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.

Conversion integration

Build a DXF to STEP XML workflow

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