Computer Integrated Design
introduction

current state
● still documentation
● want to change that
● designers must become fluent

designing with CAD● 3-D modelling
● allows change in viewpoints● 2-D by product
● object-oriented modelling● not graphic primitives● means by which represent information about a design

life cycle● brief● concept● developed detail● manufacture / construction● operation● destruction / demolition
represent and manipulategraphic and non-graphic
information

new designs● new forms
● possible through use of computers
● complex geometries ● too difficult to construct● can’t visualize otherwise● Mitchell Beyond the Tower: Constructing Complexity in the Digital Age

parametrisation● changing values of variables
● control of complex curved surfaces ● ship, aircraft, automobile design
● must be presented visually● not in mathematical equations
● NURBS● Non-Uniform Rational B-Splines

use of computers
does not upsetthe creative act

computers in design● aid with sketches & ideas
● develop themes / concepts
● facilitate production dwgs
● analyses to satisfy functional reqmnts
● speed manufacturing process
● control operation/maintenance15

3 aspectsof digital representation in design
● digital expression of form● way in which sketching & physical modelling can be transformed into digital representation
● digital integration of information● how functional aspects can be modelled so that analyses can be carried out● also includes CAD/CAM
● digital organization of office practice● presentation of information & communication between designers & clients● extent of change of work practices

CAD toolsare
whatever designersmake of them

integration& automation● automate processes in design
● automatic transfer of information
● design for manufacture● DfM, DfX

the construction process
● 4-D CAD
● CAD modelling to represent the construction process
● staged
