1. Final Assignment Air Car Chassis Design using Sketchup

2. Directions: using the Chassis specifications sheet, design a chassis. Include: - dimensions (length, width, diameter of axle holes, distance from back and bottom of axle holes Color/render chassis in wood color Animation- include at least 5 “scenes” File name: lastname_first_chassis_10a

3. Scoring Rubric 10 -All of a 7 score plus the following: - dimensions (length, width, diameter of axle holes, distance from back and bottom of axle holes Color/render chassis in wood color Animation- include at least 5 “scenes” 7- rectangle dimensioned with axle holes File name: lastname_first_chassis_10a

4. 1. Open blank sketchup draw a rectangle from the origin to a size of 5 1/2” by 1 ½ “ by ¾” First draw a rectangle to the size above 5.5”,1.5” +enter Then delete the person Now click on ‘zoom extents’

5. 2. Make rectangle ¾” high Use ‘push/pull’ Type in.75” +enter Add dimensions

6. 3. Add axle holes Using ‘tape measurer’, begin at the bottom front right corner point- click and then move (not drag) the tape measurer along the vertical line until you reach ¼” Click to create a reference point at ¼” Then click and drag with the tape meas. across the front to the left edge

7. 4. Create holes Click with Tape M. and drag along bottom to ¾”, make mark Drag up with Tape M. to inter- sect Use the circle tool – make a circle with diameter of 3/16” *TYPE IN.09375”

8. 5. Label circle dimension and extrude the hole to the other side of the block Delete the dashed construction lines using the eraser tool Use the dimension tool to label the diameter of the circle

9. 6. Extrude hole Use the push/pull to extrude hole to the other side of the block A-while holding in the Push/Pull, type in 1.5” +enter

10. 7. Repeat for the other axle hole!

11. 8. Trim off/shape chassis A- from the top view, shape wood (careful to keep your design “within specifications”) Use the line tool- draw lines at the front and back to remove material- careful not to “cut” into the axle holes!

12. 9. Modify chassis design We will use the tape measurer to make construction lines. These lines will help us remove material from between the axles. We want a thickness of ¾” from a size of 1 ½”. So 1 ½” – ¾” = ¾” ¾ divided by 2 is 3/8. End result is that we want to remove 3/8” from each side of the rectangle

13. Click and drag with the tape measurer from the edge of the chassis to 3/8”

14. Do the same on the other edge

15. Now use the line tool to draw on the chassis and use the construction (dashed lines) for reference

16. Now use the push/pull tool to remove material

18. Add a wood color

19. Animation 1.Rotate to a wide view of your design 2.Go to ‘view’, ‘animation’, ‘add scene’ 3.Then zoom in a bit and make another scene 4.Add at least 5 scenes total 5.As you work on this, click ‘play’ to See how your video looks

20. Hand in the File! 1.Lastname_first_chassis_classmod <<<(10a or 9b) 2.Rename your file after you close the file “drag and drop” your file into our drop folder
