I'm really sure this is the place to ask about DAZ|Studio, but...

Neither Poser, nor DAZ|Studio are Modeler applications.  You ca'nt create a meshform, from scratch, with either application. i.e. Carrara, Wings, Blender 3D, Maya, Lightwave, 3D Stufio Max, etc.

Instead you are always importing other meshforms, but wether or not the imported figure stays the same depends on how adapt you are with the Poser Magnets, Morph Dial Spinning, Material Room prowess, etc.
