Forgive a mini-hijack of the thread please, but Michael's code fragment prompts a related question.

I am seeking to write a script to simulate bending metal barstock based on the method described in the attached file. The first step of the method is to find the red lines tangent to two curves, but I'm not thinking that getTangentsToDir() is going to help me find such. Am I wrong, or are there any other tangent methods that might help? I reviewed the V4 and V5 beta notes but didn't find anything promising.
