Hi Michael,

>>Is that kind of self-intersecting geometry what you would consider a proper result?<<

I put forward a possible way to work, not that intersecting geometry produced from that are correct. You will have problems with this type of construction, but I still say that attempting such miter based on one intersecting bisector will not work well.

Here is that model I posted(before) again, but with the accuracy upped a little to attempt to produce a more straight profile.
