The following materials have been created to support teaching and learning in this topic.
Feel free to use anything you think may be useful.
​
Most documents will have a version number, so you can track what has been uploaded.
The course book is a companion to the CAD challenges, with over 70 questions to challenge your CAD knowledge.
​
A series of CAD challenges are provided below.
These cover all the skills required for 3D CAD modelling at this level of Graphic Communication. 
I have a series of videos covering the modelling techniques in this unit. If you are using Parametric CAD, the processes and approaches are generally the same regardless of the platform you are using. 

If you want specific versions made, you can email me and I will see what I can do. :) 
​
These are also available on YouTube.
