How to 'machine' an assembly?

I like to make a cut in an assembly that intersects several parts. The parts come from different part studio's so that it is not possible to do a boolean operation in one part studio.

Has someone a suggestion?

    I'm not 100% sure what you are asking for but it seems that in-context modelling might be your friend...

    In the example you see two identical blocks/parts assembled/glued together. I like to drill a hole, identified by the red marked sketch, in this assy. 

    When I drill the hole as suggested by edit in-context, then I get the part like shown below which is not the solution I wish. To be clear: I do not like to see the hole segments in the part in the part studio.

    For reference see: https://cad.onshape.com/documents/888da41ee74f5b788d05c4bc/w/81367712fdd18c359c14b441/e/6aebbcff6889f0254d64e2a3

    I think in that case you have to use derived to bring the parts into another part studio.  An assembly cannot modify part geometry.

    Sorry that does not make sense to me.
    What I discussed here yesterday was just an example. In real life I like to make a hole into a roof. See picture below: the red marked hole in the green Through All direction in assy B.

    This is what I think I have to do:
    1. Create a new part studio A
    2. Derive all the part that are intersect by the virtual square hole into that studio and transform them to exactly the same position as in the assy B. That's a lot of precise work.
    3. Make the red sketch and intersect them Through All. See next picture.

    4. Remove in the assy the parts that were derived in part studio A
    5. Insert  part studio A into assy B on the right spot.

    Is this true? When this is the way to do things up till now then a enhancement should shine at the horizon.

    So I voted for https://forum.onshape.com/discussion/1334/assembly-level-extruded-cut-feature.
    That is the enhancement that I like to have because it is what happens in the real world.

    Thanks for the idea of Copy in Place. However, it's still necessary to create extra assies. So, I'm still looking forward to assembly features.
