This is the first theme I have written in a foreign forum.  This is my qustion:  I have created the road net.The road made of two node and one line. Now I want put my road net on the terrain.But the terrain is wavy. If I put the road on the terrain,some faces of terrain shelter the road.How can I resolve the problem.Thank you so much.
