I have been designing a project case which consists of a main body and a cap. The main body has six "fingers", four of which are drilled at the end, to accept the end cap screws.
I created the body which I was happy with, then went on to construct the cap in the same design page. That was also fine until I offered the cap up to the main body in order to check alignments. It then became one body and I can't find any way to split them back apart again.
I have twice tried to upload the screen grab but it doesn't want to display.
