extrude, lathe modifiers generate geometry from splines. New geometry works with geometry modifiers, materials, modifier stack. Splines integrated with octree manager, clickable. two new spline types, Tsection and Lsection. Lathe is first modifier to use transform of child object to control deformation. Much like 3DSMax subobject. Line object is first object to give per vertex control to user. First attempt to hack into transform tool to allow per vertex manipulations
