For an example, the bookcase side to top joint consisted of a rabbit on each surface (for a large glue surface.) I wanted the rabbit to be 1/2 of the width of the ply and that dimension deep. It's sort of hard to explain without drawing it on a piece of paper.
I cut the parts to size and then cut the rabbits and it was important the depth and width were exact. There is undoubtedly a more efficient way of doing what I did, so that is something I need to explore.
