Our firm is converting from AC9 to AC15. We have a lot of projects where we had 1 PLN and 4 different LBK files. (1 for each individual building in a 4-lot development. This utilized the same details but different floor plans.) Now we've converted to AC15, I'd like to know if there is a way to have multiple layout books within the single pln file. I tried to search the forum and couldn't find anything. My local dealer doesn't know it either. He suggested using subsets, but they're not the same as different books (total sheet count would be for all sheets in the 4 subsets, instead of just the one building, etc.)
I'd really appreciate any pointers to a solution or a workaround!
