Read ACIS SAT / SAB for PLY conversion
A ACIS SAT / SAB-to-PLY workflow combines the ACIS SAT / SAB reader with the PLY writer. Use it when the receiving application needs PLY 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.
Select the polygon data required by the PLY consumer
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 a polygonal derivative with the OCCT PLY interface. Agree on the mesh and property fields needed by the consumer: the PLY extension alone does not guarantee compatible color or other per-element property handling. Keep assembly and CAD metadata separately when it has no destination mapping.
Validate the PLY 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.
Reopen the PLY in the downstream processing tool and compare units, bounds, surface coverage and the expected properties. Native PLY support in the catalog is write-only; this route does not imply a native PLY reader for the reverse direction.
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.
