Well, it is really tough to try and come up with a definition that works in all cases.

Like with this curve here:



If the diameter is the part where pieces of the curve are closest together, does that mean that the diameter is located in the little bottom part of this curve?

Well, the tough thing is that once you start taking in generic curve input, I have to try to consider what to do when given curves like that.

I think that generally to make it work would require focusing on a thickness type value instead of a radius/diameter type value. It's kind of a different set of UI than what Pipe does right now with radius values.
