Final Assignment Air Car Chassis Design using Sketchup

1. Final AssignmentAir 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 sketchupdraw a rectangle from the origin to a size of 5 1/2” by 1 ½ “ by ¾” • First draw a rectangle to the size above5.5”,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 dragalong 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 inthe Push/Pull, typein 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 Rotate to a wide view of your design Go to ‘view’, ‘animation’, ‘add scene’ Then zoom in a bit and make another scene Add at least 5 scenes total As you work on this, click ‘play’ to See how your video looks
