That's one impressive explanation there Michael, thanks a bunch! :) it was very helpful and i can't figure out whyi couldn't get the same result as you did even tho i tried that function. In other words Merge in Moi is more powerful than in Rhino 4 ..running some simple tests now here while typing a reply i do see it works better than in Rhino, how sweet is that! :)

I can't see what would need to be changed on this feature now

Btw, great tip about copying and pasting models between Moi and Rhino. Thank you!! i had no idea that was even possible but it'll save a ton of hdd space and time :) very useful feature.

Cheers!
