Freeform modeling with “OpenSubDiv” Modifier in a parametric way (3ds max 2016)

This video shows you how to model a cantilever chair in a parametric way with “EditPoly(Animate)” and “OpenSubDiv” Modifier in 3ds max (2016 higher) out of a box. OpenSubDiv is a very easy way of freeform modeling.
If you want to work with a specific material thickness, than it´s best to start with a Line” or with a “plane” (Polygone) and add thickness at the end with “Shell-Modifier” (Straighten corners).

Convex Faces
If you have convex faces in your geometry like in this example below, than you should add an “TurnToPoly” modifier underneath your opensub+creaseSet-modifier and enable the option “Keep polygons the polygons convex”. (klick on the picture for bigger resolution)
