def=defines a group of vertices on which separate operations may be performed

Flash3DInstance..model[modelID].createVGroup(newVGroupID, vertexArray);

The format for the vertexArray is: [vertex0, vertex1, vertex2...]

&sam=

//takes the cube model and skews it using a VGroup


myWorld = new Flash3D(270, 200, 0);

c = myWorld.newModel("myCube", "cube");

c.createVGroup("topSide", [0,1,4,5]);

c.translate(50,0,0, c.vGroup["topSide"]);

c.rotate(0,30,0);

myWorld.render();
