I do not have vault installed and I am trying to add sub files to my project. As of now my project has to find many of my files and I do not want to copy and past them into my project folder as this will mess with my parts numbering system. I want only one part / assembly file per part. I assume that you can do this with the project dialog box or some other system tool I just can not seem to figure it out.
add libraries that point to where the parts you are wanting to "add" to your project are located
this will allow you to use those parts, but not modify them
