Thanks Dave its the exact thing i was looking for.

I have an assignment where we create a grid on an A3 paper then put that into sketchup. My problem is I'm trying to make a curved fold as seen in the images below.


And this has to be made on the plane.
Here's the original grid and the area in which im trying to fold

If any of you have any idea of how I'd do this itd really help me.
Thanks
