OCCT conversion workflows

RVM to FBX

Convert RVM to FBX 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 FBX

The RVM-to-FBX route uses the RVM reader, mesh preparation and the FBX 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.

Prepare mesh geometry for FBX delivery

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.

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 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 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.

Conversion integration

Build a RVM to FBX workflow

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