Introduction to mechanical CAD is a course that will teach you how to create real-life objects that perfectly match your projects.
Imagine that you have finished an awesome Arduino or Raspberry Pi gadget. It works great, but it sits on your desk, with wires exposed, buttons and other components poking of a breadboard.
Wouldn't it be great to be able to design a custom enclosure of your gadget? An enclosure that perfectly matches the physical characteristics of your gadget, with its buttons, screen, switches, and openings for cables?
This course will show you exactly how to do this.
Using DesignSparck Mechanical from RS Components, the largest high-service distributor for engineers across Europe and Asia Pacific, this course will teach you basic mechanical design and CAD skills. With these skills, you will be able to create things that you can bring to life with your 3D printer, or through many online printing services like Shapeways and 3D Hubs.
In this course we assume that you are a complete beginner, with zero prior experience in mechanical design.
Step by step, we will teach you the terminology, design skills and CAD software know-how so that by the end of the course you will be able to create and bring to life your own designs.
The course starts by introducing you to the 3D workspace, looking at the basic DesignSpark Mechanical design features, and explaining how to use the calliper.
Then, we show you how to use 2-dimensional primitive shapes, like lines, circles and polygons, to create more complex shapes.
After that, we get into 3-dimensional space and start to create solids based on the 2-dimensional shapes we created earlier.
We help you consolidate this knowledge by walking you through a realistic design project. In this project, you learn how to create a typical Arduino gadget enclosure with all the expected typical features (like openings for cables, switches, and internal mounts for the board and its shields). We also show you how to properly export your design for printing, and even how to order a high-quality print from popular online services (so you don't even need a printer).
As with all the Tech Explorations courses, we are here to help you in this exciting learning journey. As a student of this course, you will have access to the Questions and Answers board and interact with the instructors. You can ask questions, and make comments or suggestions. We are love to talk CAD!
