Final AssignmentAir Car Chassis Design using Sketchup

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

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 colorAnimation- include at least 5 “scenes”

7- rectangle dimensioned with axle holesFile name: lastname_first_chassis_10a

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’

2. Make rectangle ¾” high

• Use ‘push/pull’

• Type in .75” +enter

• Add dimensions

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

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”

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

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

7. Repeat for the other axle hole!

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!

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

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

• Do the same on the other edge

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

• Now use the push/pull tool to remove material

Add a wood color

Animation

1. Rotate to a wide view of your design2. Go to ‘view’, ‘animation’, ‘add scene’3. Then zoom in a bit and make another scene4. Add at least 5 scenes total 5. As you work on this, click ‘play’ to See how your video looks
