Unit Description and General Aims

The unit means to enhance engineering expertise and confidence in Computer Aided Design (CAD) to not only conceive innovative and efficient designs but also to communicate these designs to customers and manufacturers via AS1100-101 standard detailed work and assembly drawings.
The student will be introduced to the history and principles of Mechanical Computer Aided Design and will then undergo an advanced study of modern Manufacturing Process and costing structures as well as the environmental impact thereof. This knowledge will enable students to evaluate and select manufacturing processes for a particular application. The students will also be equipped with advanced modelling skills to purpose design parts for specific manufacturing processes and complete cost studies. Further skillsets will be honed to set up and evaluate motion simulation of assemblies and create photorealistic renderings to communicate their ideas to their customers.
The students will attain an in depth knowledge on Additive Manufacturing processes enabling them to evaluate these technologies against user requirements, and configure and export their design for rapid prototyping.
