3D Thumbnail and Mass Properties Support for Sub-assemblies
3D Thumbnail Generation for sub-assemblies at all levels is not supported through Remote Thumbnail Worker. Therefore users will not be able to extract mass properties from 3D Thumbnails generated through Remote Thumbnail Worker.
3D Thumbnail Generation and mass properties extraction of CATIA V5 & Inventor sub-assemblies at all levels are supported though WVS only.
