I am using two different pipe sizes in my design (8" and 15"). I setup one pipe size for the 8" pipe and the changes I make for the 15" pipe shows up in the 8" pipe dfm file. I make the changes back to the 8" pipe and then the 15" shows the same as the 15" pipe. I used to do this all the time and for some reason the two different dfm's are over writing each other. I always import and export the dfm before working with the other. Am I missing a step somewhere in defining these two dfm's? I am using LDD 2006.
