Read ACIS SAT / SAB for IGES output
A ACIS SAT / SAB-to-IGES workflow connects the ACIS SAT / SAB reader to the IGES 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.
Choose the geometry to deliver through IGES
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.
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
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.
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.
