Lesson 7: Editing Your Drawing Modification Procedures
Overview
Although we'll cover some more advanced drawing commands and techniques in later chapters, the first six lessons have made you comfortable with AutoCAD's basic approach to 2-dimensional drawing. But you probably still feel a bit clumsy with some of your work. This comes partly from the newness of AutoCAD to you, partly from the need to erase and redo an effort because of small mistakes, and partly from the need to draw the same thing over and over (in great Sisyphean efforts) as you did the remote's buttons in our last lesson's exercises. Additionally, you can't create some more complex drawings that might be simple on the drawing board given templates and an electric eraser.
In this lesson, we'll tackle several commands meant to save drawing time and effort. There are many commands to cover, but you can relax, they're not difficult.
We'll divide the basic modification routines into two groups: the Change Group, which will include commands designed to change an object's appearance or basic properties, and the Location & Number Group, which will include commands designed to move or duplicate existing objects.

7.1.1 Cutting It Out with the Trim Command
You'll often find it easier to draw one long line across an area and then cut away the extra pieces than to draw several shorter lines. AutoCAD designed the Trim command to remove the "extra" bits of lines and circles. Here's the command sequence:
