Creating Solid Forms

In the following sections, you’ll begin to draw the object shown later in the chapter in Figure 24-19. In the process, you’ll explore the creation of solid models by creating primitives and then setting up special relationships between them.

Primitives are the basic building blocks of solid modeling. At first, it may seem limiting to have only eight primitives to work with, but consider the varied forms you can create with just a few two-dimensional objects. Let’s begin by creating the basic mass of your steel bracket.

First, prepare your drawing for the exercise:

1. Open the file called Bracket.dwg. This file contains some objects that you’ll use in the first half of this chapter to build a 3D solid shape.

2. If you aren’t already in the 3D Modeling workspace, select 3D Modeling from the Workspace Switching tool or the Workspace drop-down list in the Quick Access toolbar.
