  1. My lisp program runs the offset command, then immediately uses entlast to get the newly created polyline and add it to a selection set. There is a bug using this method, though, since offset creates multiple entities any time the offset distance is large enough to make it collide with itself. I am trying to find a way to get those additional polylines, but entlast only grabs the most recent. I am at a loss. The only things I can think of right now are to either write my own custom offset routine or to select everything in the drawing before and after the offset, then deselect the selection from before. Both methods sound inefficient. Does anybody have a better way of going about this? I found a few posts where people asked similar questions about this problem, but each one found a workaround specific to their case instead of addressing the issue of getting more than one recent entities which are output at the same time. For reference, here is what I'm talking about by multiple entities being created when it self-intersects:
