I don’t know why I’m having so much trouble getting the order of operations right but I want to take object 1 (which is larger), insert object 2 half-way into object 1, then intersect faces with model. Then I want to delete all of object 2 so that I’m left with the negative space.

No matter what order of grouping, ungrouping, exploding, not exploding, I do not get the smaller object 2 to leave negative space. I only get the outline of the shape on the surface.

When I search for how to intersect with faces, it doesn’t mention anything about grouping or ungrouping, and yet with both exploded I have the same problem.

Does the smaller object have to be inserted all the way through the larger object for intersect with faces to work?

Thanks for any advice.
