I am having some issues with my surfaces and I would appreciate some help. I used Civil 3D's grading tools to grade a small subdivision. Then, I extracted the contours, which made them polylines, and did some hand drafting on the contour lines to clean up the drawing. I then created a new surface and added the polylines to this new surface as contours. When I turn on the layer controls for my contour layers in this new surface, the layer controls in my other surfaces turn on as well. I do not want to see the contours from the other surfaces. What is going on and how do I correct it?
Credit where credit is due! Give kudos or accept as solution whenever you can.
Or keep your polylines for the file and label them up. use the surface with a no display if you need to get quantities or grade to it. You have already removed yourself 1 step from the grading objects so using the plines for final grade representation at this point is not the end of the world.
my 2 cents for what it is worth (hopefully at least 2 cents LOL)
