Hello again!

I would like to know how to add features to parts that are mated in an assembly.

Let's say I have a plate and I mate it with a cube.

Now I wont to "drill" both and have the holes aligned.

I want the hole on the plate to be fixed and then I refine the mating of the cube and I want the hole in the cube to stay aligned with the one on the plate.

Is this possible?
