is it possible to mage a "negative" of an object?
e.g. if i have a cylinder with a cubeshape(same object)poping out somewhere and do the operation im seraching for, the cubeshape will be symmetrized to pop also out in the cylinder
i hope someone understands that

I think I know what you are talking about... If possible, could you make a like paint image illustrating what you mean?

Possibly you're talking about Boolean differences?
Where you place an object (A) on another object (B), and when you use the operation, a piece of A is cut out identical to B?
