COMPUTER AIDED ENGINEERING DESIGN
Group A
Computer aided design of engineering systems. Applications in modelling, analysis, design
and manufacturing.
Computer graphics, raster graphics and interactiveness, pixels and graphic display in
computers, windows and view-ports, lines and circles, graphic data stor age and manipulation,
hardware display, input and output devices.
Geometric transformations-two, three-dimensional and homogeneous transformations,
rotation, translation, mirror, perspective, projections, etc.
Computer aided drafting. Introduction to Auto CAD-use of menus and icons, two-
dimensional drawings using auto CAD lines, circles, tangents, simple machine drawings,
dimensioning, blocks and layers, edi ting and adding text to a drawing.
Advanced auto CAD-three-dimensional drawings. Curves, surfaces and solid models,
customizing. Auto CAD, auto LISP.
Group B
Design of curves—PC, Beizer a nd B-spline curves, normal, tange nt, curvature and torsion ofcurves. Blending of two curves.
Design of surfaces, tangent and normal planes. Curvature and twist, surface patches—PC,
Baizer and B-spline, ruled and developabl e surfaces, swept a nd revolved surfaces.
Solid modeling—wire frame, constructive solid geometry (CSG) and boundary representation
(B-rep); parametric instancing. Cell decom position, spatial occupancy enumeration,
generalized sweep.
Mass property calculations—curve length, surface area, volume, centroid, mass, moment, etc.
Finite element analysis: Fundamentals of fin ite element analysis; discretization, mesh
generation, pre and post processing and simple applications.
