It's just the 3rd option on the boolean menu in addition to "intersection" and "difference". It may actually be called "union."
You can attach as many geometric pieces as you want and it will try to combine them into a single object. taz On Sep 9, 1:26 am, Grasshope <[EMAIL PROTECTED]> wrote: > thank you, taz! > > the problematic boolean objects in my script are closed and caped > BReps. i can use box to boolean them but still i can't boolean > between.
