In this example, it would be the box.
2. Change the Length, Width or Height Segments
of the surfaces where the subtraction will occur.
3. From the Compound Objects buttons, click
Boolean.
4. P erform the subtraction as you originally
wanted.
By subdividing the surface with more faces, the
Boolean operation has more faces and edges to
work with. This results in fewer long, sliver-like
faces that can produce creases or ridges.

Components
Booleans are programmed to work with two
operands, Operand A and Oper and B. If you plan
to join or subtract many objects from the object
that you’ve selected as Operand A, you must click
the Boolean button after each Operand B selection.
If you don’t, and simply click the Pick Operand
B button and pick the next object, the previous
operation is negated and the previous Operand
Bdisappears.
