Sorry BurrMan, I did not use PastePart, and I am somewhat ashamed to say that it's something that I didn't know existed, so I have more reading to do now - LOL, what did you do that for ?

Many Thanks

Martin

** Edit after reading" - A ha, another hidden little Gem, but I didn't need it in that example, did the small ones on the Hex shape and just arrayed it, then created the new cutter object for the bigger thread that was needed for the other. But these little unknown features are really handy to know .... Thanks for the heads up!
