I want to know if there is a better way to do this project than the way I'm putting it together now. Project Program: 3 Building Types, 2 & 3-story apartments. Each building steps 2' at certain points in the slab. Building Type 1 steps once, Building Type 2 steps 3 times & Building Type 3 steps 4 times I have the buildings in one file with lower & upper levels. I have all the walls set to the levels. I have all the unit types grouped. After I finalize the elevations, I plan on making 3 files and linking each building type back to a main file. I work alone, so I don't need worksets. (I think) I have not linked files before. My question is: if i updated a group, will it filter down to the linked files? Any opinion would be appreciated. Thanks.
