INTRODUCTION TO CADINTRODUCTION TO CAD

Com%uter-aided design is essentiall' &ased on a 6ersatile and %o0erful technique called

com%uter gra%hics, 0hich &asicall' means the criterion and mani%ulation of %ictures on a dis%la'

de6ice 0ith the aid of a com%uter. Com%uter gra%hics originated at the Massachusetts institute of

technolog' >M*T? in 1:5;0hen the first com%uter-dri6en dis%la', lined to a Whirl0ind 1 com%uter,

and 0as used to generate some %ictures. The first im%ortant ste% for0ard in com%uter gra%hics came

in 1:73 0hen a s'stem called S@(TCPAD 0as demonstrated at the /incoln /a&orator' of M*T.This s'stem consists of a cathode ra' tu&e >C$T? dri6en &' TB2 com%uter. The C$T had a e'&oard

and a light %en. Pictures could &e dra0n on the screen and then mani%ulated interacti6el' &' the user

6ia the light %en.

Com%uter Aided Design is the %rocess of de6elo%ing and using com%uter assisted design

tools in the design %rocess. The ad6ent of com%uters has contri&uted to significant ad6ance in

calculation, data handling and utiliation a%%lications. The a&ilit' to use the com%uters in these

a%%lication areas enhances the ca%a&ilit' of the design team significantl'. Drafting and geometric

modeling %la' significant roles in CAD. The module therefore concentrates on the general design

%rocess 0ith s%ecific consideration to drafting and geometric modeling. Three different CAD s'stems

are referred to in the module. The s'lla&us includes= historical de6elo%ment, the design %rocess,

traditional dra0ing %ractice and the de6elo%ment of the CAD industr', s'stem hard0are, com%uters

micros to mainframes, out%ut de6ices, storage, 0orstations, net0ored s'stems, e)am%les of CAD

s'stems sim%le entit' descri%tions= %oints, lines, arcs, made-edge lists, free-form cur6es, free-form

ROLE OF COMPUTERS IN DESIGNROLE OF COMPUTERS IN DESIGN

As manual design %rocess has se6eral ris factors including human fatigue and the e6aluation

of design &ased on his %re6ious e)%erience. With the ad6ent of com%uter and the de6elo%ment in the

field of com%uter gra%hics, 6arious design + manufacturing %rocess taes %lace ne0 faster rate 0ith

minimum or o%timum error. The &elo0 figure sho0n the im%lementation of com%uter in design=

*m%lementation of com%uter in the design stage &ecomes the su&set of design %rocess. Ence the

conce%tual design materialies in the designer mind the geometric model starts &' the a%%ro%riate

CAD soft0are. The choice of geometric model to CAD is analogous to the choice. The 6arious design

related tass 0hich are %erformed &' a modern com%uter-aided design s'stem can &e grou%ed into

four functional areas=

1. "eometric Modelling2. (ngineering Anla'sis

3. Design re6ie0 and e6aluation

4. Automated drafting.
