Part 6

Module 31 Competency Test No.6 Open Book

Learning Outcomes

When you have completed this module, you will be able to:

  1. Within a three hour time limit, complete a written exam and the lab exercises without the aid of a key.

The AutoCAD 3D 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 31-1

Time Allowed: 3 Hours

Drawing Name Template Units
AutoCAD 3D Lab 31-1 3D Layout English Inches

Step 1

Start a new drawing using the template shown above. Save the drawing with the name: AutoCAD 3D Lab 31-1.

Step 2

Draw the polylines on layer: Pline.

Step 3

On layer: Solid 1, draw a solid model of the object shown in the figures. (Figure Step 3A and 3B)

Figure Step 3A
Completed Solid Model – SE Isometric View


Figure Step 3B
Dimensioned Multiview Drawing

Step 4

On layout: Module Layout C, use the SOLVIEW command to create the three viewports of the model.

Step 5

On layer: VPORT, using the MVIEW command to create viewport. Set the view, in the viewport, to SE Isometric and the visual style Realistic.

Step 6

Set the scale of all four viewports to 1.25 and lock their display. (Figure Step 6)

Figure Step 6

Step 7

Use the SOLDRAW command to change the three multiviews views to 2D views.

Step 8

Set the current space to Paper and fill in the titleblock. (Figure Step 8)

Figure Step 8

Step 9

On layout: Module Layout D, using the SOLVIEW and SOLDRAW commands, create the three multiviews of the model.

Step 10

On layer: VPORT, using the MVIEW command, create two viewports. Set the visual style to Realistic and orbit them to match the figure the best you can by eye.

Step 11

Set the scale to 2:1 for the multiviews and 1.5:1 for the isometric views. Lock their display.

Step 12

Change the color of the layers so that the object lines are red and the hidden lines are blue. (Hint: See Module 30, WORKALONG: Creating 2D Drawings from a Solid Model, Step 16)

Step 13

Turn layer VPORT off.

Step 14

Set the current space to Paper and fill in the titleblock. (Figure Step 14)

Figure Step 14

 Step 15

Save and close the drawing.
