That would be the essential outline of the tutorial I was looking at the other night (and now can't find...) but there was additional step involving using a cylinder as a guide to help in lining stuff up and scaling your imported object.  Ack!  I really should do this to some of my favourite bits and pieces for fitting some of the less forgiving items with the FBMs included.

Bookmarking this for the day I lose my mind enough to try it.  Maybe I should get the straight jacket and padded room ready first. :p
