Overview of Creating 3D Solids and Surfaces

Three-dimensional solid objects often start as one of several basic shapes, or primitives, that you can then modify and recombine. A 3D solid or surface can also be the result of extruding a 2D shape to follow a specified path in 3D space.

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.

About Solids Based on Other Objects

You can also create 3D solids and surfaces from existing objects.

The following methods are available:

Use Visual Styles with 3D Objects

Solids and surfaces can be displayed in one of several visual styles that are applied to the viewport.
