1 Activity 5.1B Dragster Assembly Drawing Purpose The excitement of seeing your design become a product that you can see in 3D is about to become a reality for you. In this activity, you are going to learn how to create an assembly of your dragster that will show it in 3D and give you the look and feel of seeing how your dragster may look when you actually craft it in the Science and Technology Unit. Equipment Computer with Inventor software Dragster Design sketch Work completed from Activity 5.1A Dragster Design Lab Axle, front wheel, and rear wheel files saved to the same location as your dragster body design Engineer s notebook Pencil Procedure In this activity, you will use the dragster you designed in Activity 5.1A Dragster Design Lab. Be sure you know where the files are stored and how to retrieve files from your computer storage area. If you do not remember, ask you teacher before working on this activity. 1. Open Inventor. 2. Select File, New, Click on "Standard.iam." 3. An assembly window will open. 4. Click on Place Component located in the Assembly Panel. 5. Select from your GTT folder the car you designed in Activity 5.1A Dragster Design Lab. Right Mouse Click Done to accept the part. 6. It is important for the dragster car body to be placed first, as it should be the grounded part. Look in the browser area of the screen to check to see if there is a tack located in front of the part. If there is, you ve grounded this part. If not, right click on the part and check Grounded. 7. Select the file titled Axle and place two axles on your assembly space. 8. Select the file titled Front Wheel and place two front wheels in the assembly space.

Fig. 1 Beginning Dragster Assembly 11. In the Assembly Toolbar panel, select Rotate Component. Rotate one of the front wheels until you can see the hole that the axle can fit in. Next, select Constraint. Did you rotate the wheel so you can see the whole? GTT Design and Modeling Unit Lesson 5 Activity 5.1B Dragster Assembly Drawing Page 2

3 12. From the Constraint pop-up, select the INSERT icon (See Figure 3). Fig 3 Assembly of wheel and axle 13. Click on two parts, the wheel and the axle and their assembly points as shown in Figure 3. In the Offset portion of the pop-up window, enter (-.25), then Click Apply (See Figure 4). Insert Icon Fig. 4 Offset portion Apply Button GTT Design and Modeling Unit Lesson 5 Activity 5.1B Dragster Assembly Drawing Page 3

4 14. Do the same with the Rear wheel and the other Axle. 15. Next, use the Constraint tool and use the INSERT icon to install the wheel and axle assembly into the car body as shown in the Figure 5. Set Offset to Fig 5 Assembly of wheel to body 16. Since you are inserting the axle into the car body, be sure that the OFFSET value is set to Repeat for the front and rear wheels. 18. If your dragster resembles the one in Figure 6, you are almost finished with creating the Dragster Assembly.

5 19. Click the Universal Rotation tool on the Standard toolbar and rotate the whole vehicle into a position so you can see the axles sticking out through the body of your dragster on the side that needs wheels. 20. When your dragster has been positioned, use the Move Component tool to orientate the Front and Rear Wheels that you have yet to assemble to the axles protruding through the body..

6 21. Select the Place Constraint tool. Click on the Insert icon. Click on the two items to be joined together as shown in Figure 9. Be sure to set the Offset to (-.25") and don t forget to click Apply. Fig 9 Assembly of last two wheels 22. Change to isometric view. If all went well, you've assembled your first dragster, on a computer, that is. WOW!! I did this!! Great!!!! GTT Design and Modeling Unit Lesson 5 Activity 5.1B Dragster Assembly Drawing Page 6

7 Conclusion 1. Why is creating an assembly of a design important? 2. So far, you have created a 3D model of your dragster on the computer. What do you think would be different about creating a prototype out of real wood or other material? GTT Design and Modeling Unit Lesson 5 Activity 5.1B Dragster Assembly Drawing Page 7
