I am trying to use the Beam, polyline option. I draw thepolyline then use the beam, polyline button and then hit P and select thepolyline. It then ask Delete selected objects Yes/No ( I have tried both). Thenit says System exception without special treatment has occurred. I have had myUCS turned all different ways but It will not draw it. It works if I usethe same button and just pick my points but it worked before. I used this in AS2010 and it worked. The item i am drawing its an L shaped bracket for a ladder.
