Booleans stuck with Cannot resolve entities

Hi,

I am working on extending an STL and am trying to make the floor part thicker.

I created a large cubiod to intersect with the derived shape (stl) to add it add the bottom.

Every boolean (or boolean plus) operation fails with "Cannot resolve entities" when hovering over the target. I cannot select any object.

Without the boolean, the history looks ok (but ugly because I am not skilled and STL base ;-).
Curious what a workaround could be?

    I think I found a solution. Booleans do not directly work on individual extrudes or derived, but only work on full parts. Also, you cannot select the target by clicking in the part list, but you have to select it from the 3d view.
