I did work in Project A (old) and now I downloaded Project B (new) on to my server. With all the work I did in Project A, such as adding families, working on a sheet, elevations, floor plans, ceiling plans, etc. how can I import all that work into Project B? I also need to load a Sheet Template from my server on to my Project B?

Can't you just copy them from project browser? 

can you help me out...how do you do that?
