Create a .rvm file from PDMS then open Navisworks Manage. Open the .rvm created from PDMS.
You will need Navisworks Manage, Simulate, or Review to open and convert rvm file to nwd or nwf file types.
Hope this helps
You just need to to a standard DB listing and save the file as a .att file instead of a txt file. Then if the .att and .rvm reside in the same folder with the same title when you open the RVM file in NW it will read the data as well.
