I have a 3d solid of a piece of HSS and angle iron. The HSS cross section is square with rounded corners. When viewed isometrically and plotted, the round corners are not visible. I have tried Dispsil and Hideprecision to try to correct but it still doesn't show. Also, a piece of Lshaped angle iron with two holes has lines running between the holes when plotted but aren't there when you look at the file on the screen.
These pieces werer created in Microstation and Exported to a .SAT file and then imported into Autocad.
Thanks
