So go to your stove, pull off the knob, and use it as a reference. As you learn along with this course. Before we dig into learning about 3D design in a CAD program, let's take just a moment to think about 3D objects in general. Before computer-aided design programs, design information was recorded by engineers and draftsmen on paper. This way of thinking is a great foundation for thinking about objects in 3 dimensions. An orthographic projection is a way of representing a 3D object in 2 dimensions. Let's look at an orthographic projection of a house. The elevation is the front view. It's what we see if we look at the house straight on. If we rotate to the side, we see the side view. One more rotation and we see the back. Let's go back to the front elevation for a moment.
