Prepare RVM geometry for PLY
The RVM-to-PLY route uses the RVM reader, mesh preparation and the PLY 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.
Select the polygon data required by the PLY consumer
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 a polygonal derivative with the OCCT PLY interface. Agree on the mesh and property fields needed by the consumer: the PLY extension alone does not guarantee compatible color or other per-element property handling. Keep assembly and CAD metadata separately when it has no destination 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 PLY in the downstream processing tool and compare units, bounds, surface coverage and the expected properties. Native PLY support in the catalog is write-only; this route does not imply a native PLY reader for the reverse direction.
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.
