Before
you begin: First, create a “autoCAD_6” folder
on your network space for this assignment. Save all of
the following drawings into this folder.
The contents of this
assignment: In this
assignment, students will be learning how to use the POLAR and RECTANGULAR ARRAY commands, which helps to make copies of objects
rotated around a central point or in placed in rows and columns.
The
Tutorials: Before beginning, review the
following Tutorials:
The Problems: DIMENSION the
challenge problems as they are in the book!
 DRAWING 1: Page 238, Problem 6. (Draw this cooling fan. Create the
center circles and use POLAR ARRAY to copy the tiny circles 3x around
the center. Then, create one blade, then use POLAR ARRAY to copy it
to the other two locations.) STUCK on this problem? Here is a VIDEO WALKTHROUGH from Mr. B. This is an older version of AutoCAD, but the principles are the same.)
 DRAWING 2: Page 231, Figure 165 (top of page) (Draw this head gasket. Use the RECTANGULAR ARRAY to make your copies of the circles. MIRROR top of figure to bottom. Estimate all DIMENSIONS.
 DRAWING 3: Page 243, Problem 3. (Draw the two crossing spokes,
then use POLAR ARRAY to complete the circle.)
 DRAWING 4: Pages 232233. (Create the chair drawing as seen on page 232, using proper dimensions. Then, using the RECTANGULAR ARRAY, create the seating layout at the top of page 233. Distances between chairs is listed in the middle of the page.)
 DRAWING 5: Page 922, Problem
33. (This problem isn't as hard as it looks. Make the inside circles
on a diameter 3.5 circle. You don't have to dimension this problem.
This was a challenge problem a couple of weeks ago. If you have completed
it already, it should be MUCH easier to do now!)
 DRAWING 6: Page 239, Problem 8. Using RECTANGULAR ARRAY, create this air vent diagram. Estimate dimensions.)
 DRAWING 7: Using the RECTANGULAR ARRAY command, recreate the lockers in the photograph below. Include as much detail as possible! Estimate DIMENSIONS. CLICK ON THE PHOTO FOR A LARGER COPY OF THE PICTURE FOR DETAILS!)
 DRAWING 8: SKETCH PROBLEM Using pencil and paper, SKETCH a design for a set of custom wheels for a car (see examples below yours should be AT LEAST as complex as the figures!). Dimension, using your personal experiences and estimation, as needed. In AutoCAD, create a dimensioned drawing of your custom wheel, using the POLAR ARRAY command.
 CHALLENGE PROBLEM NINE: Page 920, Problem 31. (A tough problem, Lots
of trimmed circles and POLAR ARRAY.)
 CHALLENGE PROBLEM TEN:
Page 923, Problem 35. (Draw this figure. The hardest part of this
figure is figuring out how
to make the jags
in
the outer edge if the blade. The information is all there.
Use POLAR ARRAY as needed. You don’t have to DIMENSION this
one)
 CHALLENGE PROBLEM ELEVEN:
Replicate the figure below:
Submitting Your Work: COPY
your “lastname_autoCAD_6” folder to Mr.
B.’s M: Drive Drop Box Folder for your class period.
