OCCT conversion workflows

RVM to XCAF

Convert RVM to XCAF through a mesh workflow. Prepare geometry, map supported data and validate the result in the receiving application.

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

Prepare RVM geometry for XCAF

The RVM-to-XCAF route uses the RVM reader, mesh preparation and the XCAF writer. Choose the geometry and representation required by the destination application.

Read the AVEVA PDMS Review Model with the RVM interface. Select the plant areas, equipment or geometry needed by the destination rather than exporting unrelated portions of a large review model.

Build and store an XCAF document

Prepare polygonal output from the imported geometry, retaining suitable meshes or tessellating supported surfaces. Check model placements and coordinate scale before merging parts or constructing a destination scene.

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.

Validate the converted model

Include small fittings and curved equipment as well as large structures in the comparison. Keep plant identifiers and engineering properties separately when the target cannot represent them.

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.

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.

Conversion integration

Build a RVM 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.
