Prepare ACIS SAT / SAB geometry for FBX
The ACIS SAT / SAB-to-FBX route uses the ACIS SAT / SAB reader, mesh preparation and the FBX writer. Choose the geometry and representation required by the destination 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.
Prepare mesh geometry for FBX delivery
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 mesh geometry with the commercial FBX interface. Prepare the supported scene and placement mapping required by the receiving application. Check appearance and other attributes individually rather than assuming all source properties have an FBX writer mapping.
Validate the converted model
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 FBX in the destination and compare scale, orientation, geometry coverage and placements. Verify the actual version and property mapping needed by that application. Retain the engineering source for information that the scene derivative cannot carry.
For repeated jobs, retain the source, preparation settings and representative output checks. Discuss this conversion with the input files, destination application and required geometry and attributes.
