I would like to implement an Autolisp routine to simulate the command "fence copy", already implemented in microstation. The idea is drawing a rectangle in autocad, and copying to another file just what it is inside the rectangle. I usually do this step by step, i.e.,
-Draw a rectangle
-Select the rectangle
-Trim fence all the entities that are outside the rectangle
Does anybody know how to implement such an action in Autolisp?
thanx in advance : )
