SOME OPENING TUTORIALS: We are going to be doing some figures that require the use of the OBJECT SNAP and POLAR TRACKING tools in AutoCAD. Before attempting any of these problems, watch the following video tutorials regarding the use of those two commands:

A lot of the challenge and the “fun” of AutoCAD is figuring out exactly how to complete a drawing. As an example, please follow along on the following video tutorial where Mr. B. completes the first problem of your assignment today, RED BOOK, page 33, Problem 1.

YOUR ASSIGNMENT: DRAWING 1: Page 33, Problem 1. (You just went through this tutorial above. Save it to your “lastname_AutoCAD_2” folder, so you can get credit for it.) Save as drawing1.dwg.

DRAWING 2: Page 33, Problem 2. (This is a modification of the first problem. CHANGE the figure so that the tall rectangles in the problem are 5.0 instead of 4.0 units tall! Save your changes as drawing2.dwg.)

TWO MORE QUICK TUTORIALS: We are also going to learn a little bit about the AutoCAD CIRCLE and TRIM commands for use in the next couple of problems. Watch the next two Tutorials regarding these commands, then do the following problems:

NOW, THE REST OF THE ASSIGNMENT: DRAWING 3: Page 79, Problem 4. (This problem is not as hard as it looks! RADIUS of trimmed circles on the pill shape at the bottom of the figure should read R0.25 )

DRAWING 4: Page 80, Problem 6. (ONLY DRAW the front of this plate, you do not have to draw it in 3D)

DRAWING 5: Page 82, Problem 8. (Assume that the center circle is centered between the semi-circle on the left and the square on the right.)

DRAWING 6: Page 119, Problem 1. (This is an OBJECT SNAP Problem. I threw it in just to be sure you were paying attention. Make sure to use your OBJECT SNAP MIDPOINT!)

DRAWING 7: Page 119, Problem 2. (Make sure your OBJECT SNAP-TANGENT is turned on to find the right and left sides of the circle.)

DRAWING 8: Page 902, Problem 2. (A Line Problem. Format for inputting angled lines is “@distance<angle”. This might be tough if you weren't too strong on Polar Coordinate Lines. Do your best to figure it out!)

DRAWING 9: Page 903, Problem 3. (Make sure that your OBJECT SNAP- TANGENT is turned on to find the tops and bottoms and sides of your two circles.)

CHALLENGE PROBLEM- DRAWING 10: Page 907, Problem 9. (There is some math involved here to figure out some of the dimensions, don’t be afraid to use a calculator.)
