I have a hole that i will need to put on several different part models, it is not a simple hole, it is somewhat shaped like a key hole and has a unique lead in on both sides of the thru hole.

is there a way that a feature geometry like this can be saved and be repeated in multiple models as to not repeat the work every time? or can i create a solid that can be subtracted without in a part without going into an assembly?

Thanks in advance for any suggetions
