Read OCCT BRep for ACIS SAT / SAB output
A OCCT BRep-to-ACIS SAT / SAB workflow connects the OCCT BRep reader to the ACIS SAT / SAB writer. Select the model items and output representation needed by the receiving application.
Read native OCCT BRep shapes from BREP or SHAPE files. This provides geometry and topology for modeling or tessellation. A standalone shape file is not an XDE document and should not be assumed to contain assembly names, colors or materials.
Translate precise geometry into ACIS
Use the imported shapes directly for a precise CAD writer, or generate surface triangulation for a mesh writer. If the input contains open shells, faces or wires, select the geometry appropriate to the target instead of assuming every shape is a solid.
Use the ACIS writer for supported BRep geometry and select SAT or SAB for the receiving application. The published component description lists output through ACIS version 7; confirm the delivery and recipient version. A mesh-only input needs another route rather than an implied reconstruction of smooth CAD surfaces.
Check the ACIS SAT / SAB result
If application-owned labels, placements or appearance must accompany the shape, supply them explicitly in the document passed to the writer. Keep this enrichment distinct from information read from the BRep file.
Reopen the file in the recipient and check topology, surface coverage, units and supported attributes. Include translated curved surfaces and multi-body models in the comparison. Reading a file successfully is only the first check when the next task is a modeling operation.
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.
