RVM format is used for projects made using AVEA PDMS software that contain 3D models of power plants, thus rvm to obj conversion is probably just export of the rendered meshes to OBJ format.
Certain 3D modeling tools and converters list RVM format as supported, so such export is most likely doable. We have not found any information about formats supported for direct export in AVEVA PDMS though.
