I created a DWG with Civil 3D. When it is viewed with LT or TrueView the contours for the surface disappears. I checked the detail switch on the VIEW tab but it did not seem to make any difference.
Is this a function of LT and TrueView?
Solved! Go to Solution.
Another option might be to make sure that the PROXYGRAPHICS variable is set to 1 before saving from Civil3D.
