The commands used in the creation of 3D solid objects were discussed in the previous two chapters. In practice, most 3D models cannot be created using a single step of object creation. The reason for this is the fact that practical 3D models can be complicated and rich in detail. Hence, the real-life modeling process involves the creation of simple 3D objects that are close to the desired final shape, and then combining/modifying the simple objects that have been created and adding details to them using the modify commands. The set of modify commands starts with simple object manipulation, such as moving or rotating the object, the performance of standard Boolean operations, such as combining and subtracting, and a set of other specialized editing commands, as we will see in detail in this chapter.

So, to sum up, by the end of this chapter, we will be able to do the following:

• Use basic modify commands
• Use Boolean operations on 3D objects
• Work with solid editing commands
• Work with face editing commands
• Work with edge editing commands

Let's now begin by exploring basic object manipulation for 3D bodies in AutoCAD.
