I am looking for a transformation / CSG that is the opposite of bounded
/ clipped by.

for example, I have 2 boxes, (X dimension only, for example)

#declare Box1 = Box {<1>,<3>}
#declare Box2 = Box{<2>,<4>}

where 2-3 is the shared region, which I want to eliminate.

I can do merge {
object {Box1}
object {Box2}
}

and a triple object, that will contain the same place, might be box1,
box2,
box1 bounded by box2, box2 bounded by box1.

I can also do the same with difference

difference {
merge {object {box1} {object{box2}
object {box1/2 bounded_by {object {box2}}}
}

is there a function that does this operation or do I have to use these
two options?
does that triple merge bug exists in newer versions?

What "triple merge bug? Can you explain more clearly what you mean?
Also, bounded_by is an optimization feature, not a clipping/CSG feature 
like clipped_by or diffference. Your use of it as one might explain your 
problems with merge.
And to do the opposite of clipped_by, try using the inverse keyword in 
the clipping object.

Sorry I don't have time to go into more detail right now...I have to go 
to school. :-(

Eitan,

I strongly suggest you read the documentation, especially the chapters
on CSG (Constructive Solid Geometry), hollow/non-hollow objects,
bounding objects and clipped_by. All answers are there.
