Mirror.. Or Erase source objects to be exact.

Hi people.

When i use the mirror command, how can I change the default "erase source objects" to yes instead of No.

Make your own command and in CUI instruct AutoCAD to start your version each time you invoke the mirror command. I have no AutoCAD for the moment so I can't offer you a real solution, but I would write a Lisp routine to deal with the command prompts. You can suppress that "erase..." prompt at all.

Try this:

(defun c:MyMirror()
 (command "_Mirror" (ssget) "")
 (command (setq a (getpoint)) (getpoint a) "Y")
 )

Thanks fuccaro, I'll give that a try.
