3D solid objects often start as one of several basic shapes, or primitives, that you
can then modify and recombine.

About Solid Primitives

You can create several basic 3D shapes, known as solid primitives: boxes, cones, cylinders, spheres, wedges, pyramids, and tori (donuts).

By combining primitive shapes, you can create more complex solids. For example, you
can join two solids, subtract one from the other, or create a shape based on the intersection
of their volumes.

By combining primitive shapes, you can create more complex solids.3D Solid Primitives. You can create several basic 3D shapes, known as solid primitives with commands such as CYLINDER, PYRAMID, and BOX. A fast way to create 3D solids in the shape of walls is with the POLYSOLID command.to create primitive 3D solid objects.… A primitive solid is a 'building block' that you can use to work with in 3D.
