The MagicMerge does have some advantages. Connecting simple objects and then beveling the edges is quick - joining 2 cylinders of the same size at angles works great. I am trying to find the best way to create branching hoses in a natural way - think "arteries", "veins", "airways in lungs." Many anatomical systems have branching pathways - so far, 3d Kiwi's tips for manually joining them have really helped, although the process can be s-l-o-w. I have looked into plugins for creating trees, but haven't found anything that works! If you have ideas, please share.
