If you asked for AutoCAD for MAC, you are in the wrong board..

And: You are right. I am not a MAC User, but what i can read from the MAC help, it isn't an option for AutoCAD for MAC.

-

But there should be a Lispfunction to do that (and as last option, it's possible to wrote one).

We can run a short test if you like, but i am not the one who wrote whole programs for others
