In this chapter we will learn about Modifying commands in AutoCAD.

We will cover nine commands, which will enable you to make any type of change in a drawing.

First we will discuss the selection process (more advanced than we discuss in Chapter 2).

Then we will discuss the following commands:

• The Move command, which is used to move objects from one place to another.

• The Copy command, which is used to copy objects.

• The Rotate command, which is used to rotate objects using rotation angles.

• The Scale command, which is used to create bigger or smaller objects using a scale factor.

• The Array command, which is used to create copies of objects either in a matrix fashion or circular or semi-circular fashion.

• The Mirror command, which is used to create mirror images of selected objects.

• The Stretch command, which is used to change the length of objects, increasing or decreasing.

• The Break command, which is used to break an object into two pieces.

We will end this chapter with a discussion on using Grips in AutoCAD.

All of the Modifying commands (with some exceptions) will ask you the same question:

Select objects:

In Chapter 2, we learned some of the methods used to select objects. We will now expand our knowledge in this area.

All the methods we will discuss will involve typing a letter or more at the Select objects prompt.
