I am using ACAD 2012. I have created two cubes which interlock.
I have subtracted one from the other to leave a cube shape in the larger of the two cubes.
I now want to Delete where the cube which was subtracted from the larger cube, which I could do by pressing ctrl+selection of cube required.
This would highlight the cube and allow me to delete it, thus returning the original larger cube to its original state. It appears now that by pressing ctrl, I cannot select the smaller cube.
I therefore cannot obtain my original cube.
Any Ideas why this should happen?
