Thanks rclub24/Dave R, that looks like exactly what I need.

(sorry to the moderators for posting this query twice, feel free to delete the second post - newbie error...)

I'm currently trying to make an assembly manual-style diagram in which all of the grouped parts of an assembled object are separated from each other by a certain distance.

I'm sure I remember seeing a Ruby script that performs this function at the click of a button but I can't remember what it's called.

All help gratefully received.
