Hi Tore,
Jaco has documented it in the LPub4 web page.
The idea is that buffer exchange is most commonly used for removing parts from
the previous step, but what if you want to remove something from an older step?
You could use buffer exchange, but then you'd have to add lots of steps parts
again to get the rest of the model back.....
I created remove group for pneumatic and robot models, where you add one end
of a hose or cable to the model, but the place where the other end hooks up is
added in a future step. When you've added the part where the other end
connects, you can remove the old version of the cable, and put in a new cable in
the proper shape. I've seen this kind of thing in lots of LEGO pneumatic models
(my favorite :).
I never got done with move group, which would be a different way to do the
exploded views currently done with buffer exchange.
