Create 3D Solid Primitives
You can create the basic solid shapes of box, cone, cylinder, sphere, torus, wedge, and pyramid. These shapes are called solid primitives.
You can create a solid box. The base of the box is always drawn parallel to the XY plane of the current UCS (workplane).
You can create a solid wedge.
You can create a solid cone with a circular or an elliptical base tapering to a point. You can also create a cone frustum, which tapers to a circular or elliptical planar face that is parallel to its base.
You can create a solid cylinder with a circular or an elliptical base.
You can create a solid sphere.
You can create a solid pyramid. You can define the number of sides for a pyramid from 3 to 32.
You can use the TORUS command to create a ring-shaped solid similar to the inner tube of a tire.
