Some valve components are missing on the DGN 3D drawings after conversion from NWD files. I tested DGN files with Bentley Viewer V8i, Bentley MicroStation V8i and APM viewer. Valve handles are missing when DGN file is opened in Bentley tools. In original NWD file all valve components are present.
VSTS item #13587 - "Missing valve components - DGN files" was created for this. Will be considered in the testing of the new VisOps tool.
