I have recently run into problems where NavisWorks has slowed down on opening. In the past it used to open pretty quickly and only slow down if it needed to create a new .nwc file for a referenced file.
Now it appears that it is creating new .nwc files for all files on open which is really slowing down the opening of files. It really struggles when it gets to the larger structural steel files. Does anyone know of a setting that I may have changed that is causing this problem?
