OCCT conversion workflows

XCAF to ACIS SAT / SAB

Convert XCAF to ACIS SAT / SAB. Prepare source geometry, select the target writer and verify placements and supported attributes.

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

Read XCAF for ACIS SAT / SAB output

A XCAF-to-ACIS SAT / SAB workflow connects the XCAF reader to the ACIS SAT / SAB writer. Select the model items and output representation needed by the receiving application.

Read the native XCAF document with the OCCT storage interface matching its file type. Inspect document shapes, assembly occurrences and attributes before selecting the part of the document to exchange.

Translate precise geometry into ACIS

Choose BRep or mesh geometry according to the actual shapes in the document and the destination. Resolve assembly placements and map supported names and colors. Native document storage can contain application information that another CAD or scene format does not represent.

Use the ACIS writer for supported BRep geometry and select SAT or SAB for the receiving application. The published component description lists output through ACIS version 7; confirm the delivery and recipient version. A mesh-only input needs another route rather than an implied reconstruction of smooth CAD surfaces.

Check the ACIS SAT / SAB result

Check occurrence placement separately from shared part geometry. Validate transferred labels and attributes, and keep the source XCAF document when application-specific data or edit structure needs to be retained.

Reopen the file in the recipient and check topology, surface coverage, units and supported attributes. Include translated curved surfaces and multi-body models in the comparison. Reading a file successfully is only the first check when the next task is a modeling operation.

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 XCAF to ACIS SAT / SAB workflow

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