I have imported a civil CAD background for the site study that I am doing. The dwg was put into a drafting view as I am studying several sites and creating my graphics with filled regions, etc. Everytime I open the file, the site CAD that I am working with shifts to a new location, even though I have it pinned. I don't think this can be a coordinate thing because I am not working in model space. Can someone please help me with this before somebody opens this file and prints it for a client with a wonky background? Thanks for any help.
