..::cut glass modelling::..

Enlarge Screenshot Open up the cutglass_start.max scene included below; here you have a basic (partially) lathed spline that you will edit a part of then, using the Symmetry modifier, repeat around the rest of the glass. Start by adding an Edit Mesh modifier, make all of the top part of the glass edges visible, and turn selected edges to create a diamond pattern as illustrated. Make non-turned triangular edges invisible again after your edit.
Enlarge Screenshot Next, using an Edit Poly modifier, select the diamond shaped groups of polys (individually; don’t grab all of them else they will all bevel as a group) and apply a slight inset or bevel with no height; perform this on every diamond. Select the inner edges of the diamond group and, using the glass’s axis as a transformation reference point, scale these back slightly to create a subtle inset (illustrated). Finally, bevel back and weld the outer set of polys as illustrated.
Enlarge Screenshot Next, edit the side cuts as before by bevelling back and welding where necessary to clean up ( I used a Symmetry modifier to ensure that the bevel back was uniform and not to one side). Next, select all “hard” edges (this may take some time!) and apply a subtle chamfer; you will need to clean up some resulting geometry as the chamfer will produce some tri’s. Finally, using several Symmetry modifiers, complete the glass and with a final Edit Poly modifier, model in the inner-part of the glass.
