Mary, The duplication idea was correct, but most likely needed to be done via the command line for flexibility: duplicating a single object of two+ chains results in an object of two+ chains. Thus, calling rotate on the new object will rotate both chains in the new object. If you want to just rotate one of the N chains, then you need to duplicate just that single chain:
# create a new object from the original object's chain X create newObj, origObj and chain X You next need the rotate command: rotate x, 22.5, object=obj01 where this would rotate 22.5 degrees around the x axis for the duplicate object (probably called 'obj01'). You can also rotate around any given axis: rotate [ rX, rY, rZ ], a, obj01, where rX, rY and rZ specify the axis about which to rotate, a is the angle of rotation, and again, obj01 is the object. Type "help rotate" to get help on rotating. Translating is rather simple too: translate [x,y,z], obj01 where [x,y,z] is the translation vector, eg. [1.25, 0.4, 15]. Again, "help translate" for more help. Cheers, -- Jason On Sat, Jun 5, 2010 at 4:15 PM, Mary B.
