Module Description

This module introduces the learner to three-dimensional (3D) Computer Aided Design (CAD) modelling, and constructing solid models relating to parts and assemblies. The production of two-dimensional (2D) working drawings is also considered. It also introduces the role and application of computer-aided design relating to the manufacture of products. Knowledge Breadth: This module draws on fundamental 2D draughting elements and principles to develop and enhance 3D geometry. The concepts of 3D solid models along with the advantages/disadvantages of Boolean-and parametric-modelling are discussed. The benefits of features and constructions available uniquely in the 3D CAD environment will be discussed. The importance of working/production drawing layout for manufacture will be discussed. Kind: Analysis and breakdown of solid model geometry will allow the learner to approach a design problem and allow the development of appropriate design features. Know-how and skill Range: The learner will gain skills, applicable in many industrial areas, with respect to product design and 3D CAD modelling. They will include existing design geometry interpretation, model creation, part-assembly interaction, working drawing layout & presentation. Selectivity: The learner will develop the expertise in design methodically with the ability to present data to those outside the design environment. Competence Context: The learner will be able to apply the range of skills developed in this module in a range of modern manufacturing/mechanical industries. These skills could also be applied in the area of research and development. Role: The learner will be able to perform in a role of Product Design in a variety of industries, both as an individual or group-member. Learning to Learn: Through the progress in CAD software in this module, the learner will improve their basic computing skills, and also progress in appreciating and comparing similar advanced CAD technologies. The learner will also develop spatial awareness with respect to three-dimensional forms, understanding geometry in a real sense as compared to previous orthographic interpretation. Insight: The learner, both as an individual and as part of a group, will have used software throughout the module and the provision of use of software is explained. The learner will appreciate the technical aspects of software use and also the legal and ethical arguments of software piracy.

Module Aims

The aim of this module is to give the learner an awareness of the role of solid modelling in the design process and an appreciation of working drawing standards with respect to a manufacturing environment.
