I know it is a demanding process to create complex dialog boxes with dcl. ( I've been there alot ) In adition to this tedious job, lisp diaglogs are very restricted that one can not utilize them transparently with autocad use.
What I mean here that I dont think that it is possible to create smth. like the properties palette which is running along as you continue to use autocad. Or is it? is there any way to create a custom "palette like interface" with lisp or vba dialogs? thanks..
