                           Exploring the Primitive Object Types

                           In the Create panel are actually two different subcategories of geometric primitives: Standard Primitives and
                           Extended Primitives. These primitives include a diverse range of objects, from simple boxes and spheres to
                           complex torus knots. You can create all these primitives from the Create panel.

                           Starting with the Standard Primitives
                           The Standard Primitives include many of the most basic and most used objects, including boxes, spheres,
                           and cylinders. Figure 5.9 shows all the Standard Primitives.
                           Box
                           You can use the Box primitive to create regular cubes and boxes of any width, length, and height. Holding
                           down the Ctrl key while dragging the box base creates a perfect square for the base. To create a cube, select
                           the Cube option in the Creation Method rollout. A single click and drag completes the cube.
                           The Length, Width, and Height Segment values indicate how many polygons make up each dimension. The
                           default is only one segment.
