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.

Lab Exercise 21-1

Time allowed: 60 minutes.

Step 1

On layer: Object, draw the object shown in the figure. Draw all construction objects on layer: Construction. (Figure Step 1A and 1B)

Step 2

Using inquiry commands and the Properties window, find the answers for questions A to H.

For questions A to D, find the answers to a precision of 4 decimal places.

A. What is the XY coordinate location of the center of Circle A?

X- _____________

Y- _____________

B. What is the circumference of Circle A? _____________

C. What is the distance from the center of Circle A to the center of Circle B? _____________

D. What is shortest distance between the circumference of Circle A and the circumference of Circle B? _____________

For questions E to G, find the answers to a precision of 8 decimal places.

E. What are the XY coordinates of Corner D? _____________

X- _____________

Y- _____________

F. What is the length of Line E? _____________

G. What is the shortest distance from Corner C to the circumference of Circle B? _____________

For question H, find the answer in Deg/Min/Sec to a precision of 2 decimal places (seconds).

H. What is the angle of Line F? _____________

Step 3

In layout: Module Layout B, create a viewport on layer: Viewport. Set the scale of the viewport to 1:2 and lock the display. (Figure Step 3)

Step 4

On layer: Titleblock Text, fill in the titleblock. Use the AutoCAD Modules Titleblock Standards shown in Module 20. (Figure Step 4)

Step 5

Freeze layer: Viewport.

Step 6

Using the TEXT command and the answers you found for questions Step 2 (A to H), insert them on your drawing locating them by eye on the layer: Text. Insert them in Paper space. Use the text style: 2D Modules at a height of 0.20. (Figure Step 6)

Step 7

Save and close the drawing.
