The aim of this module is to provide skills in the use of computer-aided design and 3D modelling systems to solve design problems. Product designers communicate their designs through CAD software packages. It is used at all stages of the design task, from conceptualisation to production of working drawings. It provides the basis for manufacturing products. Engineers must master computer-aided design techniques in order to ensure design intent is accurately taken through to manufacture and service. In this module students will practice the techniques involved in producing advanced 3D models.

Outline Syllabus:Drawing files: load and create and edit a drawing file from source Record modifications: update the drawing and record modifications; produce updated documentation using a word-processing package with inserted views relating to modifications Produce hard copy: produce hard copy of updated drawing using scaled plots, scaled views, different printer/plotters and reconfiguring CAD software to suit Coordinate systems: manipulate co-ordinate systems to suit required geometry Correct geometry: using polylines to construct shapes for surfacing and constructing splines; using polyedit to restructure line/arcs into continuous geometry Surface construction: generate the bounded geometry required for any surface; use generated geometry to create surfaces; use of all methods of surface Facet numbers: numbers required to smooth surface; memory problems using high numbers of facets Viewing medium: use of Hide, Shade and Render to visualise the product; print or plot finish drawing; the use of different textures; lighting controls Coordinate systems: manipulate UCS and WCS to suit required geometry Solid model: using polylines to construct shapes for extruding, using polyedit to restructure line/arcs into continuous geometry; use of Hide, Shade and Render to visualise the product; applying various materials to generated slides; cutting the solids and sectioning; different lighting; textures Construction techniques: the effects of subtract, union, intersect extrude, sweep and revolve in model construction; editing the geometry using fillet, chamfer etc; using primitives to create geometry Properties of solids: using solid model to find the mass, radius of gyration, centre of gravity and surface area Printing image: generating image Dimension a solid: dimensions are correctly added to a solid composite drawing in multiscreen mode; dimensions are correctly added to true shapes previously extracted from solid composite
