How to creat a simple skin model
 

I'm a newbie. I've project to creat a simple skin model with 3-layers sturcture. Someone can tell me what skill should be used to achive this aim? Polygonal Modeling, NURBS Modeling or others? please help me!!

Like a scientific model of the skin layers? hmmm well if you want an organic feel, i would use curves and nurbs. I can't give you much advice myself but you should probably go by trial and error.

yes, just like a scientific model of Skin.
I'm trying many times by using Polygon Modeling, but I haven't successed yet.
Need I creat each layer separately? and then lap them togother?
thanks

THats odd, see for a newbie project, I would choose a nice inorganic architectural object, or maybe a car, And if you want a nice organic one, you may want to go for a hand, or a head.

just my 2 cents

sorry, i'm not very clear about your meanings.
what should i do first?

If it were me, I would define the skin layers with the texture map. Unless you need them to be separate pieces. Personally, I would use polygons. Just modify a cube to suit your needs.

Goodluck!
