really wish the manual was more specific on measuments with the various settings in poser as well.  i understand the time but i cant really corrilate the dial settings into measurements that i can understand.  this would be especially helpful with the collision settings. 

also could someone please explain in laymans turms how to work the "gravity" setting in poser.  i have looked at tutorials and still dont understand how to instill gravity to body parts of a figure so that they avatars will react is if influenced by gravity.
