Computer Aided Design 1 is a 3-hour weekly computer lab, delivered over the academic year, which introduces students to the modelling and creative design process through the use of CAD software.

This module demonstrates how to create two-dimensional (2-D) drawings and three-dimensional (3-D) models. The CAD software used is standard with architects, engineers, drafters, artists, and others to create precision drawings or technical illustrations.

Computer Aided Design 1 teaches the fundamental principles of technical drawing and modelling through an active learning environment where students are required to complete weekly assignments and also a design-and-build project at the end of each semester.

1. Use three-dimensional solid modelling software in the design of engineering components.

2. Apply engineering graphics standards.
3. Use various technical commands and be able to select the appropriate methodology (design intent) required for the creation of a solid model.
4. Create drawing files displaying orthographic layouts from the solid model as well as dimensioning and applying dimensional and geographic tolerances to the drawing file.
5. Select and use the optimum software techniques to create parts and assemblies models.
6. Use standards parts libraries for the selection of appropriate standard components in the design / assembly process. Teaching and Learning Strategies

Computer Aided Design 2 is a five-credit module, delivered via a 1.5 hr laboratory over academic year. The aim of the module is to enhance the student's skill, knowledge, and competence in producing mechanical models, virtual prototypes, engineering drawings and design documentation. Students will be introduced to specialist extensions of CAD software including Mechnical Simulation and flow analysis through which structural, thermal, fluid flow and modal analysis of designs will be conducted. Additionally, students will be exposed to more advanced features of the CAD Parametric package including Sheetmetal, Surface Modelling and Multibody Design.

Students will learn about the importance of Geometric Dimensioning and Tolerancing specification (ASME Y 14.5) in the design process and will be required to apply GD&T to their drawing files. Specifically, general tolerancing and related principles, symbology, datum reference frames, tolerances of form, tolerances of location, tolerances of profile and tolerances of runout.

In addition, students will also be exposed to other commercially available CAD packages, examining similarities in workflow and data exchange. Central to this module is a design, build and test project, where students are challenged to undertake a design challenge. Applying the skills learned in the module in a synergistic combination with rapid prototyping, students will be tasked with the physical manufacture of both functional and aesthetically pleasing designs to meet a set design challenge.

1. Reproduce complex parts and design features using advanced surface modelling tools and techniques.

2. Use rapid prototype technologies such as 3D printing and laser scanning develop and demonstrate product design ideas.

3. Use appropriate computer aided engineering extensions in order to evaluate designs from a basic structural, thermal and/or fluid flow perspective.

4. Produce functioning CAD models – while working within diverse groups – by utilising the learning assimilated in theCAD modules.

5. Produce technical reports which incorporate product specifications and controls such as dimensional and geometric tolerances.
