> Quote - Hi folks - does anyone know of a way (script, utility etc) to set everything in a scene to have the same parent, other than going through each of about 150 separate items and setting the parent individually? 

HI there is Python Script that does this and it is a real time saver!!!
Check with user "Okham".
I would offer you a copy of mine but I remember Okham made some Mac OSX specific changes to the version he so kindly
gave me.
