Hi, im trying to drape a road onto a terrain. The lines are draped but no closed face is created

Thanks for any help

By default, the draped lines are not part of the terrain group. They cut if you copy them inside it.

Not sure how you mean. Some spaces in between the roads are becoming faces. I used this tool successfully before
