OCCT conversion workflows

RVM to OBJ

Convert RVM to OBJ 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 OBJ

The RVM-to-OBJ route uses the RVM reader, mesh preparation and the OBJ 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 polygonal geometry for OBJ

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 surface mesh with the OBJ interface. Establish whether the consumer needs per-part grouping, normals or supported appearance information, and preserve any associated material resources produced by the writer. A polygon file is not a replacement for the full CAD document.

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.

Check the OBJ in the receiving graphics or geometry tool, including scale, face orientation, grouping and companion-file references. Where a flat mesh cannot retain the original assembly relationships, keep that engineering information separately.

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 OBJ workflow

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