Here is what I have....a .NWD file from the coordinator with all the clash reports for about 5 different trades.

What I want to do is make changes to my .dwg file and then "refresh" so that my NEW .dwg file comes in and updates the clash reports.

Can I do this with an .NWD? Or do I need the coordinator to send me his original .NWF file to be able to do this?

Or am I just way off here?
