Spring 2026 Sample Solution
You have made it to the end of the third workbook!
This workbook has introduced you to curves. Curves are important for making shapes. While we focused on 2D curves, all the concepts extend to 3D and will provide the basis for how we create surfaces in 3D.
Hopefully, you got here by going through every page and completing the work on it. The boxes are the most significant components. Here is a list of all the boxes and whether or not you checked the checkbox. This way you can keep track of what you’ve completed. We will not look at these checks: they are for student convenience.
List of Boxes
| Box The box name links back to the box. | Check These checkboxes indicate whether you have checked the checkbox for the box. If you didn't check the box, go back to it, make sure the work is completed, and check it. | Tag (internal) This is our "internal code name" for the box. | Kind
Kinds of boxes: view - look at the box and experiment with it examine - look at the code for the box edit - change the box's content rubric - several steps are suggested in the rubric page - form elements on page in rubric |

Handing things in…
Please check one more time that your NetID is correct:
Please tell us how you used AI tools in doing this workbook. Remember, disclosing AI usage is part of the class policy on AI usage.
In the following section, you should give attributions for any included work—for example, if you took an image or model from the web.
Check that the local store is correctly written (and the json file has moved to the correct location) - it probably changed after you filled in the AI Note and Attributions.
If you’ve done that, you are ready to submit your workbook!
Make sure to commit and push your work. Then press the “Submit” button to tell us that your assignment is ready for grading.
You are viewing the solution version of this page. Submission is disabled.
After pressing the Submit button, the File Status may say “The json file does not match the local store” because the submission time is now in the local store. You don’t have to worry about that.
If you’ve made something you are particularly proud of, we encourage you to submit it for the gallery.
Congratulations! You’ve completed Workbook 3.
