Read ACIS SAT / SAB for OBJ conversion
A ACIS SAT / SAB-to-OBJ workflow combines the ACIS SAT / SAB reader with the OBJ writer. Use it when the receiving application needs OBJ data from an existing ACIS SAT / SAB model.
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.
Prepare polygonal geometry for OBJ
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 selected surface mesh with the OBJ interface. Establish whether the consumer needs per-part grouping, normals or supported appearance information, and preserve any associated material resources produced by the writer. A polygon file is not a replacement for the full CAD document.
Validate the OBJ 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.
Check the OBJ in the receiving graphics or geometry tool, including scale, face orientation, grouping and companion-file references. Where a flat mesh cannot retain the original assembly relationships, keep that engineering information separately.
For a production pipeline, keep a representative source file and its expected geometry and attributes with the conversion settings. Discuss conversion integration with the source and destination applications, or compare the supported format interfaces.
