Let me give you a better example of what I'm trying to do. I am taking an existing job, that is very similar to my new job, and copying. I need to open the main file, and all of it's subs. What I need to happen is when I update, change, modify my new design, for the drws. to update accordingly. Keep in mind, the job is 100% detail. Which is why I need all the sub drws. Thanks
