Since this seemed to be a more Poser-specific question, I'm posting this in the Poser forum instead of the Blender forum.

 I need some help with learning to group for Poser figures when using Blender.

In a nutshell, I need to know:

a.  How to create a grouping in Blender 

b.  What to name the grouping. Do I just name it Waist, Hip, Thigh, ect. or is thaqt where I have to name it according to Poser internal names or something?
