This module further develops the students Computer/CAD skills to enable them to produce 3d models of real world products. The module will build of model complexity both externally, in terms of the ability to model more complex geometric forms and internally, in terms of attention to design detail such as clips and fasteners, part mouldability etc. Other Computer Aided Engineering technologies will also be introduced such as Computer Aided Manufacture and Reverse Engineering.

Learning Outcomes

On completion of this module the learner will/should be able to;


Produce CAD models of real world products.


Produce geometrically complex CAD models.


Model designs for different manufacture processes; metal casting, sheet metal forming and injection moulding.


Produce Designs of products taking into account process capability.


Model products incorporating design detail such as lips, bosses, clips etc.


Use assocated technologies such as Computer Aided Manufacture, Rapid Prototyping and Reverse Engineering.

Module Assessment Strategies

The subject will be evaluated by a combination of tutorials, assignments and final examination.

The student will recieve instruction in a specific area in the form of a tutorial. This will be followed by assingments where the student applies the knowledge gained. The semester will conclude with a final exam and/or project.

Indicative Syllabus


Advanced solid modelling: Creation of complex parts using lofts, sweeps, replace face, divide part and Boolean operations etc. Use of equations/variables to build design intent into model, use of design tables for the creation of families of similar parts. Bottom up and top down design. Linked parts, parent and child relationships etc.

Surface modelling: Modelling of complex curves by, derivation from planar curves, intersection of geometric features or projection of a 2d sketch onto a 3d surface.  Creation of assorted surface types using, loft, sweep, bounded. Conversion from surface to solid geometry by joining/stitching and thickness application.

Modelling for mouldability: Overview of moulding tool features, core/cavity, runners, gating, ejectors, sliding cores etc. Mould types. Criteria for designing plastic components, wall thickness requirements, minimising sink marks, weld lines etc. Use of plastic product specific functions such as Ribs, Rib networks, lip detail, thin wall. Part analysis for mouldabiltity, Core/Cavity modelling: split line detection, shutout detection. 

Design documentation. Overview of drafting fundamentals, Orthographic views, isometric and auxhiliary views. Assembly documentation: Baloon referencing and parts lists. Drafting assorted configuration, e.g. exploded views, assembly with parts hidden etc. Sectioning, exclusion of components from section, section only (elimination background detail), broken out sections etc. Component detailing, tolerances, and geometric tolerances. 

Reverse Engineering: Overview of Reverse Engineering Technologies: Automated contact scanning, Articulated arm contact scanning, laser scanning: Point cloud manipulation and refinement. Fitting cad geometry to point cloud data. Reverse engineering assignment.

Computer Aided Manufacturing: Definition of Computer Numerical controls and overview of machine construction. Cutter types and their capability. Machining strategies, Roughing, Finishing and detail machining. Cutter path generation for a variety of CAD models. process simulation. Role of multiaxis machining. Process demonstration by both video and live demonstration.

Rapid Prototypting: Overview of processes available and the advantages and disadvantages. Process demonstration.
