I tried Wings, Blender, Milkshape and Anim8or for vertex modelling . I find ... Wings' functions too esoteric . Blender's interface too complicated . Milkshape too slow in large import/export and is commercial . I find Anim8or (by Steven Glanville, Windows only) best ... It has primitives, point, edge, face tools, ... standard lathe, extrude, mirror, weld, join, ... inset, thickness, subdivision, deformer, ... a simple interface, ... And good documentation and tutorials .
