Well, presumably the correct skeleton would be selected so you could use getSelectedNodeList() or getSelectedSkeletonList() to shorten the task. If you use the node list you can use the inherits function to discard stuff you don't want: if ( node.inherits( "DzBone" ) || node.inherits( "DzSkeleton" ) { // do stuff } will make sure you don't act on the wrong thing.
