Distort a sketch like Freeform acts on a surface

I have a 2D sketch that I need to deform much like freeform does to a surface in 3D. I need to keep the sketch constrained in a plane but move certain areas on the sketch and have the other areas distort accordingly. Any ideas on how to accomplish this?

No one else has this question

What are you trying to do that you can't do with a 2D sketch of a spline?

Constrain each end of a spline, and add 1 or more spline points, and move them as required. What additional control are you looking for?

  I am matching print to tool on a thermoformed part. The process is to make a tool and form a part. After the part is formed the sheet stretches and distorts the print in a way that makes it not line up with the tool cavities. I am searching for a way to pre distort the sketch so that when it gets distorted by the forming operation it lines up with the cavities. I am not looking for software that automatically predicts this distortion. I think all I need to do is print, form, look at the result and then distort the sketch and then print again.
