1.14 - Welcome!

Class will meet every Monday afternoon. We will spend in-class time to learn a new theory or technique in the CAD software. You will be required to practice the software and principles on your own between each session. I will add new models for practice each class for you to complete. I will post a solution to creating the part or model a week later.

Getting Started:
Make an educational account on Autodesk for Fusion 360 here
Open Fusion 360, setup preferences (Z to top, default units, grid snapping, home view, mouse button settings/zoom)
Create a folder for the class materials called CAD151 in Fusion 360

Create your first fully constrained sketch in a new component
Use a few of the sketch tools to look at the 2D functionality of Fusion 360
Get to know the tools and user interface, while developing your mouse skills
Create a folder structure for class projects
Build the 4 sketches in the picture frame example following the video and included archive of dimensions

Draw a hexagon that is inscribed within a 22 mm radius circle and centered on the origin.
Finish the 4 sketches for the picture frame from the previous class.

2.04 - Sketching & Constraints

Getting Started:
Take some time to work on your journal for class, including a screenshot of your picture frame and a paragraph including some new skills learned and any questions you may have had!
We will review the previous class basic geometric shapes.
Work on detailed sketching and 3D extrusion.

For next class:
Make sure you have the correct model from class, check the models and video to be sure!
Attempt four out of the six listed drawings above, create a new component for each and use your extrude tool
Be prepared to share them with other students in class!

2.11 - 3D Modeling (CSG)

Getting Started:
Share your favorite practice drawing from the previous class assignment with another student, explain your rationale for designing it
Spend some time getting your docs up to date
Review Extrude and build Constructive Geometry Solids understanding

Supplemental Materials:

For next class:
Make sure you have the correct model from class, check the models and video to be sure!
Attempt four out of the six listed drawings above, create a new component for each and use your new CSG concepts
Be prepared to share them with other students in class!

2.18 - Parametric Design & History

Getting Started:
Share your favorite drawing from the examples with a new person in class
Find the bearingBlock.f3d file and import into your Fusion 360 environment. Make a bearing block that fits the bearing provided, with the stock and bolt provided. It must hold the bearing in on one side, but not interfere with the bearing's movement.
Design of the bearing block is up to you, but must meet the requirements, use the measure tool to build your part.

Begin designing and measuring for Project 1: Parametric Keyboard Design. Guidelines are listed below. This project is due on March 18

Project 1 - Parametric Keyboard Design: March 18
Your goal is to build a fully parametric keyboard design. This will consist of one model in Fusion and should easily be able to be adjusted based on the constraints listed. If you adjust one variable, make sure that it coincides with the proper variables to adjust your entire model. Begin your journey this week and bring questions next week. You will have some in class time to work on your design. Your keyboard must:
Contain the major keyboard keys in a QWERTY keyboard from the tilde (top left) to the CTRL (bottom right), use keyboard-layout-editor to look at designs and make your own
Set parameters for the overall size of the physical keyboard layout, the length, width, and height
Control the number of keys present on the keyboard
Adjust the sizing of the keys
Adjust the spacing of the keys parametrically

3.04 - Class Cancelled

We will not be holding class this week. Please work on your projects that are due March 18. See requirements above. This discussion board should allow you all to chat about progress and help each other out! Feel free to reach out to me as well.
Check your email for the Project 1 Discussion Post link!

3.18 - Advanced Parametric Design

Getting Started:
Please submit your project .f3d file on this submission form
Spend 5 minutes sharing your keyboard success with another person in the class, listen to someone else's for 5 minutes...
Create a completely parametric bolt and nut set...

Supplemental Materials:
Socket Cap Screw Data
Example Socket Cap Screw from Fusion 360

For next class:
Create your nut and bolt so that it is parametric and has adjustable parameters to the Screw Data table.

Use the revolve command to build half the profile, include the screw length, head height, head diameter, and screw diameter.
Include all the above parameters and the chamfer on the top edge, hex key size and depth.
Create a simple hex nut that fits the desired bolt. Make sure that the parameters from the nut and bolt match where needed...
Look at the hex size, bolt size, nut thickness, and chamfers!

If you have not finished your keyboard project, please do so ASAP! If you need to meet or want feedback please email your design or a meeting time! Don't forget to submit your final product in the link at the top of this post!
