Hi All,
I have a lisp routine to change our specific colours to another so I can quickly update old DWG colors to our new standards. The Lisp routine works great however there is a duplicate colour
So on the first run I want to change all colours 240->10 and 10->20. So on the firts run no problem. If I run it a second time then the original 240 colour will become 20, when I need it to stay 10.
I've been trying to figure out how to put in a safety to stop this second change in case anyone runs it twice accidentally but I'm stumped...
