I have created about 60 PP sheets making 5 layouts per file. There is minimal c3d labels in the file. About 6 pipe networks; 2500 feet of sewer displayed as dbl line and various utilites to plot the crossings only. the files started out opening slow, but once in behaved fairly well. as the drafters were tweaking paper space notes and plotting crossing the files appeared to degrade.
There really isn't much to the files about 6 MB each. Now they are starting to FE when switching to MS. there are 10 vports per file, MAXVPORT = 64. I tried setting vports to cache yada yada. Is there anyone setting in options that may help? what can be the problem here?
