OCCT conversion workflows

ACIS SAT / SAB to XCAF

Convert ACIS SAT / SAB to XCAF for OCCT applications. Store imported geometry with supported names, colors and document structure.

Build this conversion into your application with OCCT readers, writers and the commercial components identified below.

Read ACIS SAT / SAB for XCAF output

A ACIS SAT / SAB-to-XCAF workflow connects the ACIS SAT / SAB reader to the XCAF 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.

Build and store an XCAF document

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.

Place the imported geometry in an XCAF document and map the supported names, colors and structure to its labels. Use the native OCCT document storage appropriate to the selected XBF or XML delivery. Mesh data can remain mesh in the document; creating labels does not generate analytic CAD surfaces.

Check the XCAF 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 document in the intended OCCT application and verify geometry, occurrence placements and mapped attributes. Keep application-specific additions distinct from source properties. XCAF storage is useful for continuing an OCCT workflow, but the recipient must support the chosen document format.

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.

Conversion integration

Build a ACIS SAT / SAB to XCAF workflow

Share the source and receiving applications, representative files, required attributes and throughput. We can scope SDK evaluation or an integrated conversion service.
