it's how sub-Ds work, dude
it's like nurbs but on steroids
you can't just move the vertex and expect it to work like polygon modelling because the algorithms are different
eaech vertex is linked to other vertices the same way nurbs are
i say its on steriod because you have a lot more control over it than nurbs, you can change the level of detail (?) on a sub-d surface to showmore points or less
of you're having trouble knowing where some verteces are cuz they are inside the mesh then you should use the x-ray mode
there is a script on highend3d, i think, that you can just plug into your shelf and it toggles between xray and non-xray.
that's a "Ch" pronounced as a "K"
