I created a drawing from a part. I had to create an assembly from the part. I have added the assembly to the drawing and want to swap the reference so that the drawing uses the assembly as the primary source and the part as secondary. Currently the assembly does not feed the title block which is what I want it to do. Is this possible without having to create a new drawing? I tried switching the reference before opening the drawing but I receive a mismatch error because I am trying to switch from a part to an assembly and vice versa.
