I have done a test with Poser 7 and get 1 figure from a group of 4 primitives.

load 4 balls and move them so each ball is just toutching the next   ball 1,2,3,4

parent ball 2 to 1 , 3 to 2, 4 to 3

select ball 1 in heirarchy editor

press the button to create a figure, give it a name

the figure will be in new figures folder

delete the props

load the figure

you should get figure 1 with bodyparts ball 1,2,3,4

select  a bodypart and move the rotate dial to see it work.
