Hello all im new to all this Animation/Modeling. but i love it. i know the basics, and ive been working on a single Male model for some time its not a Great looking model or anything but im liking it.
just a Simple polygonal Model i started from a Square.

Anywhoo. My Question is after Spliting and Extruding so meny times. when i switch from Flat Shade all to Smooth Shade all. Only Some areas of the model shade correctly the rest of it stays as if it was still in Flate Shade mode.

does anyone know what i did wrong?
how can i fix this error that i may have made?

and sorry if this Question has been asked already.. i havent found anything as of yet refering to the problem im having.

oh also note if i Smooth the Model the Flat shade and smooth shade works fine afterwords. i wish i knew what the heck i was missing.
