Read ACIS SAT / SAB for OCCT BRep output
A ACIS SAT / SAB-to-OCCT BRep workflow connects the ACIS SAT / SAB reader to the OCCT BRep writer. Select the model items and output representation needed by the receiving application.
Read SAT or SAB with the commercial ACIS interface and translate supported bodies into OCCT BRep. Select the supported source version and retain the relationship between imported shapes, names and colors needed by the application.
Store imported geometry as native OCCT shapes
Use the translated BRep for precise geometry output. For mesh-based delivery, tessellate the surfaces with an appropriate chordal deflection and inspect small faces and narrow features before writing the result.
Write the imported precise shapes using native OCCT BRep storage. This route is useful for retaining translated geometry for subsequent OCCT modeling and analysis. It requires BRep source geometry and does not recover analytic surfaces from a mesh-only representation.
Check the OCCT BRep result
Include representative curved surfaces and multi-body files in the evaluation. Keep source-version compatibility and the target writer settings with the conversion record so that repeated jobs use the same configuration.
Read the BRep file back with the intended OCCT delivery and compare shape types, tolerances and geometry coverage. A standalone BRep file does not carry the complete XDE assembly and attribute document; choose XCAF storage when that document-level information must be preserved.
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.
