Introduction to CAD – Ivaldi Lesson Plan

By Mary Celestin, Intern Ivaldi.

Lesson Overview

Lesson Duration: 2-4 hours 

Lesson Level: Introductory, Late Middle School/Early High School 

Lesson Topics: On-Demand Manufacturing, Additive Manufacturing, CAD Design

Lesson Overview: You will go through an opening activity that will teach you the basics of on-demand manufacturing, a brainstorming activity to help you with your design thinking process, and a shoutout to amazing trailblazers in the field. Then you will use TinkerCAD, a free website that lets you learn the basics of CAD. After signing up and going through some introductory lessons, you will choose a project to build a design. Once you’ve completed your project you will download FreeCAD, learn how to use the software, and recreate your project from TinkerCAD in FreeCAD–software that matches professional CAD software more closely than TinkerCAD. By the end of this lesson, you’ll have a good sense of all things Computer Assisted Design!
