COMPUTER AIDED DESIGlq

By: Steve Maynard


Date: 13Jan 1987
Audience: Designgroup meeting of 1.S.A

     Tonight we are going to look at threequestions relating to ComputerAided Design.

What isComputerAided Design? Next question:Why do we need Computer Aided Design;i.e., what are thebenefits? Finally,we will lookbriefly at: How dowe implement Computer Aided Design?

The first question is:


I.WHAT ISCOMPUTER AIDED DESIGN?

A. Beforewe define the term,let's consider the three types of informationwe-dealw-ithi_n eegineexlng.

1.Text- data sheets,mat'1specs, requisitions,etc.

2.Non-scaled drawings - PHID's, loopdiagrams, junction box loading drawings,etc.

3.Scaleddrawings- give detailed information Plot Plan,piping key plan,Instrumentwiring e g


*

B . Now that we have adefinition of engineering information,we canmake a statement as to what we mean by Computer Aided Design:

"ComputerAided Designis the implementation and use of computer tools in order to increase the engineering designer's effectiveness in producing the engineering informationrequired to build a product.

"

You'll notice that the key players inComputer Aided Designare the designers themselves. The intent here isnot to replace designerswith a computer but rather to relievethem of some of the tedious, repetitious tasks that detract them fromusing their expertise inthose excercisesthat requirejudgement and experience.

11. WHY USE COMPUTER AIDED DESIGN?

A . Leverage i n competing a g a i n s t foreign competition.

1. Foreign competition i s bidding a t a f r a c t i o n our c o s t per man-hour.
a t our c u r r e n t charge per man-hour, w e must

be s e v e r a l times as e f f i c i e n t with each engineering manhour.
i s achieved through use of computers.

To remain competitive

T h i s gain i n e f f i c i e n c y

B. Shorten t h e l e n g t h of time required f o r detailed engineering and design.

1. Reduce u s e r i n p u t as the same information can be d i s t r i b u t e d i n t o d i f f e r e n t documents and/or drawings.


C. Improve product documentation.


1. L e g i b i l i t y .

2. Allows us t o alter the "look" of our drawings.

a. More varied information i n t o t h e same dr_awisgs,__Reducas~nssd

E . Capture Information.

1. Information can be s t o r e d and r e t r i e v e d in a form useful. f o r f u t u r e plant maintenance.

2. E a s e of d u p l i c a t i o n ( o r customization) of t y p i c a l documents w i t h i n a Job saves t i m e .

3. Existing drawings can serve as "go-by's" f o r f u t u r e Jobs. Greatly enhances e f f i c i e n c y .

111. HOW DO YOU EFFECTIVELY IMPLEMENT COMPUTER AIDED DESIGN?

A. As you e v a l u a t e packaged software o r consider...
