5. © 2012 Autodesk Copyright @2014 3D Systems Ltd & Teach Design Ltd Apply CAD Tools to the development of a virtual model. Using Autodesk Inventor, you are going to model your design idea. To do this, you need to employ a set of simple tools. Watching the tutorial will give you a grasp of the basics, but it is up to you to apply these tools in creative ways. The tools you will master are: - Creating a 2D sketch - Extrusion - Holes - Revolves - Fillets - Chamfers - Shells - Modifying a sketch - Exporting an.STL file Task: Watch the tutorial video, follow the basic techniques to create a simple solution, then design your own.

Returning to Autodesk Inventor, we are now going to look at using some simple design techniques to remove material. In the video tutorial, you can observe the designer removing excess material using a shell technique, which is very simple and can provide a strong yet minimal product solution. As an alternative, the designer chooses to drawn sketches on to the surface of the product, and remove material to modify the function slightly, and also remove large sections all together. Task: Consider the techniques, and try to modify your park to use less material.

7. © 2012 Autodesk Copyright @2014 3D Systems Ltd & Teach Design Ltd Export evidence of CAD to support building a portfolio. In this final tutorial video, use your virtual model to create evidence of your work. You are going to render a view, or number of views, of your product. This is done in Inventor Studio. Once you have a rendered view, you can create an Orthographic drawing. This is a front, side and top view of your product as a scaled technical drawing. You will add key dimensions of the product to the drawing. Task: Follow the instructions exactly, and produce a rendering and orthographic drawing.

9. © 2012 Autodesk Copyright @2014 3D Systems Ltd & Teach Design Ltd How well have you met the lesson objectives? Plenary Apply CAD Tools to the development of a virtual model. Adjust a virtual model to reduce production time. Export evidence of CAD to support building a portfolio. How did you apply your CAD tools to the virtual model you created? How does reducing material and complexity reduce print time? What images and files have you produced to evidence your design work? What else could you create?
