I have done it nefore via Windows Explorer. Go into the project directory
and under DTM, find your surface name, then view the files in the surface
folder .. select them all, right click, then on the bottom left uncheck the
"Read Only" box.
You can try to delete file locks via Project Manager too, but I imagine its
the read only thing.
There wasn't a read only file, so I deleted the locked file. At least the surface isn't locked anymore. But it still crashes trying to gen a profile. I thought the locked file was why I couldn't gen a profile.
After I sample the surface and try to make a profile where it's a quick profile or full profile I get a fatal error and it kicks me out. I thought it was because of the locked surface. Could it be because someone else used Civil 3-D to do cut and fills?
I couldn't tell you a thing about Civil 3D, I use land Desktop. Sorry. As far as it crashing, I've never ran into a problem with CAD crashing due to locks. I have had cad crash with surfaces or profiles and it's usually due to bad data in the surfaces but again, I don't know much about Civil 3D.
