Description

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!

Who is the target audience?
  • Makers that want to learn how to create custom objects, like project boxes
  • Anyone interested in learning the basics of mechanical design using computer aided design software
  • People new to 3D printing
  • Anyone that already owns or considering buying a 3D printer
  • Anyone interested in prototyping new product ideas

Meet Nick Christodoulou, our director of operations. He has experience across an array of disciplines including CAD and CAM systems, CFD and FEA Simulation Software, Object Scanning and Reverse Engineering, 3D Printing / Rapid Prototyping, and CNC Machining. Octane Motorsports, L.L.C. is a U.S. based company that was conceived with the goal of providing the collector and exotic car markets with quick turnaround services for one-off, hard to find parts.


Nick has been an avid explorer and maker since childhood. He would take apart radios, telephones, TV's, tape decks, and toys to study them and see how they worked. A large part of his personal inspiration stems from reading books about the life and many inventions of Nikola Tesla. He wishes to instill a similar drive and spirit of invention / making into others.


Nick is an expert in the field of Additive Manufacturing technology and has always found inspiration in the world of engineers, inventors, makers, manufacturers, and their products. He enjoys sharing his knowledge and experiences with others in the maker and engineering communities.


His hobbies include Amateur (Ham) Radio, configuring and tuning Engine Management Systems, designing and assembling Forced Induction systems, HPDE / Road Course Racing, Travel, RC craft, and Scuba Diving.
