Read DXF for IGES output
A DXF-to-IGES workflow connects the DXF reader to the IGES 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 geometry to deliver through IGES
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.
Transfer supported BRep curves and surfaces with the OCCT IGES writer. Select the geometry and topology representation accepted by the receiving CAD application. This is a precise-source route; a stored visualization mesh does not supply the original analytic geometry.
Check the IGES 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.
Reimport the IGES into the destination and check units, open boundaries and surface coverage. Determine whether downstream sewing or healing is required. Keep richer assembly relationships and attributes separately when the selected IGES mapping cannot preserve them.
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.
