BEFORE YOU START: Create a new folder on your network space, called FUSION_360. In this FUSION_360 folder, create another new folder called “LESSON_6”. You will need to EXPORT your drawings as .F3D files and save it to your LESSON_6 folder for grading!

THE RELEVANT VIDEO TUTORIALS: You will NEED to watch this video to be able to complete this assignment.

PROBLEM 1: Complete the "HANDLEBAR" exactly as in the video and SAVE YOUR DRAWING WHEN COMPLETE AS HEX_NUT.F3D to your LESSON_5_FOLDER.

PROBLEM 2:

SUBMITTING YOUR WORK: I will grade all of the problems for FUSION_360_LESSON_4 Directly out of your folder on your COLOR Drive.

GRADING: I will be grading FUSION_360 work in the following way. I will be grading your completed assignments and figures each week. As there are only going to be 3 figures for each assignment, all assignments will be worth 60 points, 20 points for each of the practice problem and the independent problems.

POSSIBLE KEYCHAIN PROBLEM:

1. Design a Single Chain Link:

   • Start a new sketch on a plane.
   • Draw the profile of a single chain link (typically an oval shape).
   • Use the ‘Extrude’ tool to give the profile thickness, creating a 3D body.

2. Add Fillets for Realism:

   • Apply fillet features to round off the edges for a more realistic chain link appearance.

3. Create a Component from the Body:

   • Right-click on the body in the browser and select ‘Create Components from Bodies’ to make the link a unique component.

4. Duplicate the Link:

   • Use the ‘Copy’ and ‘Paste’ commands to create a second chain link, or use the ‘Rectangular Pattern’ tool if you plan to make multiple links in a straight line.

5. Position the Second Link:

   • Move the second link into position so that it interlocks with the first, using the ‘Move’ tool or by setting up joints.

6. Create a Joint:

   • Use the ‘Assemble’ tab and choose ‘Joint’.
   • Select the motion type as ‘Revolute’ to allow the links to rotate relative to each other.
   • Pick points on both chain links that will be the pivot points of the joint.

7. Test the Joint Movement:

   • Drag the components to ensure that the joint allows for the correct motion.

8. Pattern the Links:

   • Use the ‘Pattern’ tool (under the ‘Create’ tab) to create multiple copies of the chain links.
   • Select ‘Component Pattern’ if you're patterning the assembled components.
   • Choose the pattern type as ‘Circular’ or ‘Rectangular’ based on the desired chain layout.
   • Adjust the quantity and direction to fill out the length of the chain.

9. Add Joints to Additional Links:

   • Repeat the process of adding joints to each new pair of links that interlock.

10. Inspect and Validate the Chain:

    • Check the full chain for proper alignment and movement.
    • Make any necessary adjustments to the joints or link positions.

11. Finalize the Design:

    • Once satisfied with the chain's design and motion, save your work.
