How to Add Surface Control Edges?

Hey there,

I have a planar surface, which I received by using PlanarSrf command on previously build curves. This surface represents a road. How do I add control edges to different parts of road, so I can manipulate them in order to change elevation of a certain part of a road? Ideally this edges would be perpendicular to road as I displayed on attached image.

Thank you in advance.

Hi Jonathan -

It all depends on how much you want to change that object. If it’s a single trimmed planar surface now, you’ll probably have to split and then rebuild some of the parts. If you have the terrain these roads will be on, you could pull the surface onto that terrain…

Thank you for your response.

How do I put surface on a terrain? Do I use the project command? And if part of a terrain has an incline where the road should be put on, how do I even the road, so both sides of the road are on the same level, so they incline up the hill or decline down the hill the same way, if you understand what I want to say.

Thank you again in advance.
