I have polylines representing roads, walks and walls - all at 0 z value. I created a topography, including various z values, by converting countour lines and using the patch command.
I want to project the polylines to the surface, so that I can adjust the topography. When I project the polylines, such as a road, to the topography surface and then edit the z values of the road using control points, the road decouples from the surface. I want the z value of the road and surface to move together.
For example, if the road is on a cross slope I want to raise the downhill side of the road poly - and bring the surface along with it - to flatten that section of road across the slope.
Is there a way to project the polys to the surface and lock the two together to simultaneously reshape both using control points?
Do you have a better approach?
Thanks and I really appreciate any help.
