Create a subdivision surface from a polygonal cube

You begin the lesson by creating a polygonal cube. You'll convert this cube to a subdivision surface that will be the foundation of the hand. The reason for starting with a polygonal surface and converting it to a subdivision surface is that you can thereafter edit the object's shape with more versatility. You can edit with subdivision surface tools and polygonal tools.
Select Create > Polygon Primitives > Cube  . In the options window, select Edit > Reset Settings. Then enter the following values and click the Create button.
Width: 8
Height: 2.5
Depth: 8
The resulting polygonal cube is roughly proportional to the palm of a hand.
Rename the cube, pCube1, as LeftHand.
To convert the polygonal cube to a subdivision surface, select Modify > Convert > Polygons to
Press 3 on your keyboard (to select Display > Subdiv Surface Smoothness > Fine).
Also press 5 (to select Shading > Smooth Shade All).
With the Smoothness set to Fine, you can see that the conversion to a subdivision surface creates a rounded, smooth shape. By pressing 3, the subdivision surface is displayed more precisely in the scene view. This gives a closer approximation of what the surface will look like when you create a rendered image of the scene.
As an alternative, you could have chosen a rough smoothness (press 1) so that Maya processes your editing changes in the scene view more quickly. Regardless of the smoothness in the scene view, surfaces always are displayed precisely in rendered images of the scene.
