Carlson Civil 2021 in Autocad 2020
So I had a profile cause a crash. when I reopened my drawing I got a popup saying my profile had crashed, do you want to use OpenGL rendering... so I said yes. Now my profile looks very pixelated and my vertical curves are gone. When I try to recreate the profile again, the new version looks the same and gives incorrect elevation data, so it's not just a display thing.
Anyone got any ideas on how to fix this?
