Hi all, i have been designing a roundabout, and i have managed to get the corridor into a rebuilding loop. I am wondering if there is anyway to interrupt this loop without cntrl alt del kill civil 3d. I made a link look at a finished surface profile, and have the corridor to automatically rebuild, so each time it rebuilds it thinks the profile has changed, so it goes about rebuilding itself. If this is the case (which i think it is), does anyone know how to stop the loop?!!!??? PS I have found it quite amusing actually, silly me
