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?

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)
