Use "Complex tools" to model a Human Character
Level Advanced
 

SETUP THE CHARACTER:
1- Start with primitives: 1 sphere for the head, cylinders for arms, legs and torso. 2- Shape primitives into more sophisticated models by inserting isoparms, pushing and pulling CVs, scaling and translating Hulls. 3- Place models in position to connect them together.
CREATE A SEAMLESS CHARACTER:
1- Detach Surfaces and prepare for later Stitch 2- Rebuild Surfaces: Always use 0 to # of spans (before attach, fillet, or stitch) 3- Freeform Fillet between surfaces.  4-  Rebuild  Fillet (Fillet becomes Chord Length, you need to rebuild to 0 to # of spans) 5- Delete History, to clean your surfaces. 6-  Global Stitch (to align Isoparms) settings on : -closest knot- equal parameters- normals- 7-  Attach second surfaces, Attach using isoparms :         (to hide seams use blend/ to keep corners, use : connect/ multi knot ) 8-  Place seams where we can't notice it much . Use this technique to connect eyes, ears, fingers, legs, arms or even nose.
SETUP CHARACTER FOR ANIMATION:
1- Use wrap deformer (creates a low resolution polygon version of the model) 2- Connect NURBS model to polygonal model (quads/ tessellation: general/ per span # of isoparm/ 1 to 1) 3- Have all Normals face the same direction 4- Edit polygons, Combine (merge, saw multiple edge tools) 5- Simplify model as much as possible. 6- Use low resolution polygonal model to setup the Skeleton.
