For intersection, multiple objects within a single set are first unioned together into a single object, and then those 2 unioned results are then intersected with each other.

Does that explain what you are seeing there?

For intersecting 3 objects in that way you may want to do that with 2 separate runs of the boolean intersection command, or possibly use merge mode instead.

Not posted the following so there

I have 3 objects, but in reality we can put any numbers of object for "the second set"!
So that I ask if the order of selection of objects has or has not importance for end intersection (first being selected) :)

I don't think it should make any difference.

The thing that makes a difference is what set you put the "extra" object in.

For instance if the 2 sets are ( 1 2 ) isect ( 3 ) or ( 1 ) iset ( 2 3 ), that can make a difference.
