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 36-1 OPEN BOOK

Step 1

Open the drawing: AutoCAD 2D Lab 29-3. (Figure Step 1)

Step 2

Using the SAVEAS command, save the drawing with the name: AutoCAD 2D Lab 36-1.

Step 3

Draw the three doors, shown in the figure, anywhere in Model space. Draw them on layer: 0. Ensure that the color assigned to layer: 0 is black/white. (Figure Step 3A and 3B)

Step 4

Create a block from each of the three doors that you drew in Step 3. Use the following:

A Name each block as shown below the drawing.

B Set the BLOCK command to delete the objects after creation.

C Set the base point of the blocks as shown on the drawing.

D Give each block a description and set the Block units to Inches.

Step 5

On layer Doors, insert the door blocks to match the door opening size. (Figure Step 5)

Step 6

On layer Hatch, insert the pattern: Net in the areas shown in the figure. Set the scale to match the hatch to the figure the best you can by eye. (Figure Step 6)

Step 7

On layer: Boundary, draw a closed pline, at a width of 1″, around the 4 rooms and the hallway. Ensure that you snap to the corners of the walls. Find the area of each closed pline in Sq Ft to two decimal places of precision. Record the results. (Figure Step 7)

Step 8

Enable layout: Module Layout C. On layer: Viewport, create a viewport at a scale of 3/8″=1′-0″ and lock the display. In Paper space, on layer: Text, add the room name and square footage that you found in Step 7. Using the standards in Module 20, fill in the titleblock. (Figure Step 8)

Step 9

Turn layers: Viewport and Boundary off to complete the drawing. (Figure Step 9)

Step 10

Change the current space to Model. You drawing should match the figure. (Figure Step 10)

Step 11

Saved and close the drawing.
