heyas; okay, for symmetry to work, the parts on either side of the body have to have the same name, except the leading 'l' and 'r'. so 'lClaw' and 'rDrill' won't do it. also note that the arm/leg symmetries ONLY do the old arm/leg body parts (thigh, shin, foot, toes). this is why leg symmetry doesn't work with figures that have buttocks.
