It's a pretty basic thing that you can do in both Word and Photoshop, but I can't figure out how to do it in art rage. Basically I have a straight line that I want to warp into a curve. I tried using the french curve stencils and they're pretty crap for me tbh. What I'm wanting is to draw a curving road into the distance, so draw a couple of straight lines and then warp them. How does one achieve that?

In fact, come to think of it, can you curve the perspective grids?
