AutoCAD 2D is written in competency-based modules. This means that you do not complete each module until you have mastered it. The open book module contains a comprehensive lab exercise to test your mastery of the set of modules you have completed. As it is intended to be checked by your tutor, there is no key. If there are parts of this module that you have difficulty completing, you should go back and reread the module or modules that contain the information you had trouble with. If necessary, repeat the lab exercises as many times as necessary until you fully understand the material.

If you are completing this book:

• Without the aid of an instructor, complete the lab exercise.
