well the idea of combining the legs to the body and the body to the head was during the stage when the model was in polygons before getting converted to subDs. the problem i had was once i combined them all and tried to convert to subDs to then go on to define the model and get more detail i got errors about nonmanifold geometry and my subDs were left whith huge holes in them. so i didng bother going to poly and combining.

id rather have done so to get a smoother model but as im new i didnt know hot to fix the problem i had hahah.
