um, wow, misterviet, if i understood a wiord u just said i might have been able to help u, and from what i gatherd, u dont even know what a mesh is, or anything else.
helpfull terms:
MESH-THE ACTUAL MODEL STRUCTURE THAT CREATES THE SHAPE!!!!(this what ur talking bout)
skin - the outside, and actual skin like thing. makes model visible, and gives it texture, color, and that stuff\
thats what u end up with is meshes and skins
face- the prat of the mesh that is solid, and makes up part of teh bodie (strunt between edges)
edge- lines that make up the outline, and stuff of the model, not (structure for planes, which is setn between two point)
vertex- a point, that designeates the end of a line or lines. when moved it re aranges the edge whcich changes the plan and alters the model
most of the changing of the model, and structure is doen with the vertex, but when u need u can add a face between edges, or make an edge between verexes
if ur using gmax, READ THE TUTORIAL ITS PREETY CLEAR, but its realy there is a list of like qube, plane, sphere, cylinder, cone. . . and so on. this is a preset things, but it is not required, u can add vertex and vertex to make a line, and line on line on line on lone . . . to make a face, ui get the point.
