This mini-unit teaches students how to get started with CAD using Onshape. Onshape is a free, browser-based CAD software that is a great alternative to Autodesk or Tinkercad. It offers the professional, parametric approach to CAD that Autodesk offers while allowing students to create 3D models from any device (Windows, Mac, ChromeOS, smart phone) connected to the internet.

This introductory section is great for students who have learned the basic sketch tools in the software. It contains step by step instructions with screen captures of the software to help students visualize the process.

Skills covered:

-Creating a basic extruded part

-Adding fillets and chamfers to a design

-Creating a basic revolved part

-Designing an original car

3 basic assignments and a design activity are also given. The design activity gives the students the ability to show creativity while using the tools learned previously. All assignments listed are linked to a working document on Onshape to allow the students to see the finished product in 3 dimensions.
