If you save the figure to library after fiddling with the joint parms for practice, be sure to save it with a new name - otherwise you'll have those ruined joints in that figure always! Of course, once you have the joint parms you want, you should indeed save the figure. Personally, I always load a standard figure and immediately save it to New Figures library as "WIPfigure" and then load WIPfigure when I want to practice or experiment. Have fun.
