I have AutoCAD 2013 and run the new CADduct2013. I do my set up in Project Navigator and do a 3-d structure using the CADduct. I am doing my first drawing using the new 2013 set-up(updated from ACAD 2010 and CADDuct .157.) I have never had it run this slow, it is taking about 30-60 seconds a command! All I do is rotate a 3-d view and have to wait around a minute. I have nothing running in the background and I even tried taking it off our server. No matter what I do it is still running extremely slow. I have a Dell XPS, 8GB RAM, and an I-7 Processor. Any Ideas???
