Just a note, my experiance with SU is that unlike CA, if you dont set it up properly, it simply won't work. Meaning if you use "follow-path" or push/pull and you run into a situation like this, it will simply stop you dead in your tracks. I suppose at least CA shows "best it can" as Bill said. BTW, he is right about this miter and the cuts.
One of the strongest apps I know for this type of detailed work is Vectorworks, but going back-and-forth between apps has proven to be no time-saver IMO.
