I want to know if there is a plug in to do the following.

I have a drawing with an A and B side. I want a field that would change A and a field that would change B. Then the drawing would be updated according to the numbers entered.

This is basically for making custom shaped metal. So there would actually be a length, width and depth.

If there is a way to draw it in 3d that would be even better. I would then price the product by the entries and a material selection. I know that I can do this without the drawing component using attributes, but I was hoping to have some interaction too.
