Fillet and Chamfer, but avoiding the obligation for the segments to "be consecutive or separated by one segment"

[aitorm]

I like how the Fillet and Chamfer commands also join lines. I use it a lot. I also like how if you Fillet or Chamfer the very last segment of the polyline with the first segment, it does close de polyline. But I don't understand why if I try to Fillet or Chamfer one segment that is not the last one with the first segment, it doesn't do it! it says: "Lines belonging to polylines must be consecutive or separated by one segment"

So I would love if you could help me create a LISP that allows me to do this, maybe eliminating every segment that is after the one I want to chamber. 

Thanks a lot.

When drawing a pline use the "C" option rather than "Enter" then it will close the last point to the first point. See if that fixes.

Thanks for your answer. I know I can do that, but it is not what I a
looking for.

Post a dwg that does not work.

I would want to see an image or drawing of a "before" Polyline showing where it starts/ends, the places you want to pick on it, and the "after" result you intend.  I think I understand what you want, but this would confirm or correct my assumptions.
