you must be missing something. I always draw profiles in the specific dwg, not in my base plan, therefore I must utilize the data shortcuts. First your drawings that have the project info need to be attached to a project. Then the datashort cuts need to be made. I think you have both of these. Then you need to be in the drawing that you want the shortcuts to be in, go to your projects in the masterveiw of your toolspace and to your data shortcuts, right click on the desired shortcut then select create reference. It will ask you a couple things after that like layer, name, style etc. After that you should be good.
