Hello,

Is there a 2D version of Boolean difference where you can subtract one 2D shape from another?

http://docs.mcneel.com/rhino/5/help/en-us/commands/booleandifference.htm

For example, you have have a three 2D rectangles and the largest one overlaps with two smaller ones. You need to subtract the two smaller 2D rectangles from the larger one in order to have a unique “E” shaped profile which you would then extrude.

Thanks for any guidance you can provide.
