Document Summary
Computer aided engineering (cae) is a vast subject that comprises of computer. Aided design (cad) and computer aided manufacturing (cam). Cad can be further sub divided into finite element analysis, computer aided. Computer geometric modelling is the mathematical representation of an object"s geometry using software. A geometric model contains description of the modelled object"s shape. Since geometric shapes are described by surfaces, curves are used to construct them. There are number of software programs that then allow the mathematical description of the object to be displayed as an image on the monitor. These are the various types of computer geometric modeling techniques as of date: Uses lines, arcs and curves, as if the object shape were made with pieces of wire. Wire frame models are representations of a 3d object using edges, lines and vertices. It is the most abstract of the three modeling techniques.
