I have an assembly that changes daily and drawings made at each step of the way using .dwg format. The problem is, that when I add something to the assembly, it addes it to the drawings already made and as a result losses dims and notes that I made. Is there a way to set the dwgs so that all new items added to the model automaticly are no visible in the drawings that were already created. I spend a lot of time changing old drawing to what they used to be. Thanks.
