The AutoCAD 2D book was written with competency based modules. What that means is that you have not completed each module until you have mastered it. The Competency Test module contains multiple choice questions and a comprehensive lab exercise to test your mastery of the set of modules that you completed. There are no answers or keys supplied in a Competency Test module since it is meant to be checked by your instructor. If there are any parts of this module that you have trouble completing, you should go back and reread the module or modules containing the information that you are having trouble with. If necessary, redo as many lab exercises required until you fully understand the material.

If you are Completing this book:

• Without the Aid of an Instructor, complete the written test and the lab exercise.
• In a Classroom with an Instructor, the instructor will give instructions on what to do after this module has been completed.

Lab Exercise 26-1 OPEN BOOK

Step 1

On layer: Object, draw the object shown in the figure. Draw it anywhere in Model space. (Figure Step 1)

Step 2

Using the MIRROR command, mirror the object and make the necessary changes to match the figure. (Figure Step 2)

Step 3

Complete the object by erasing and extending all lines so they are all continuous in length. This object will be referred to as the original object in this lab exercise.

Step 4
Copy and scale the original object at a scale factor of 0.25 to a location anywhere in Model space. The smaller object (scaled object) will be referred to as the scaled object in this lab exercise. (Figure Step 4)

Step 5

Complete the following steps: (Figure Step 5)

A Copy the scaled object to the coordinates shown. Stretch it to match the dimensioned drawing.

B Copy the scaled object to the coordinates shown. Stretch it to match the dimensioned drawing.

C Copy the scaled object to the coordinates shown. Stretch it to match the dimensioned drawing.

D Copy the scaled object to the coordinates shown. Stretch it to match the dimensioned drawing.

E Copy the scaled object to the coordinates Stretch it to match the dimensioned shape.

Step 6

Complete the following steps: (Figure Step 6)

F Copy the original object to the coordinates Scale it to match the dimensioned drawing.

G Copy the original object to the coordinates shown. Scale it to a scale factor of 5.

H Copy the original object to the coordinates shown. Scale the two outside ones to a scale factor of 0.5 and the center one to fit.

I Copy the original object to the coordinates shown. Rotate it 45 degrees and scale it to match the the figure.

Step 7

Complete the following steps: (Figure Step 7A and 7B)

J Draw a 1.4 diameter construction circle at the coordinates shown. Copy the scaled object to the coordinate shown. Array the object to match the figure.

K Draw a 1.4 diameter construction circle at the coordinates shown. Copy the scaled object to the coordinates shown. Array the object to match the figure.

L Copy the original object anywhere on the drawing. Scale the object to match the given dimension. Rotate it 45 degrees. Using 2 polar arrays, complete the diagram shown below. Move the finished objects to the coordinates shown in the figure.

Step 8

Complete the following: (Figure Step 8A and 8B)

M Draw a construction circle at the coordinates shown. Copy the scaled object to the four locations shown. Execute the ARRAY command, four times, to match the figure.
