This lesson will prepare your students for a design challenge in the next lesson. Fusion 360 is free to use for educational institutes and is the leading software in schools for teaching 3D CAD modelling. This lesson pack includes step by step screen shots of every skill being taught and also video tutorials of how to complete the tasks. This will allow students to work at their own pace and allow them to make rapid progress. The lesson starts out by explaining how X,Y and Z co-ordinates relate to the concept of 3D CAD modelling. This builds upon the beginners knowledge of understanding that a Gcode is a set of co-ordinates created from a 3D model that has been sliced into layers. The learning then progresses into how to create basic 3D shapes using Fusion 360. Each task comes with a video tutorial to support the learning. This lesson will enable your learners to understand the key features of 3D modelling allowing them to build upon this in the next 2 lessons to create models to 3D print.
