Presentation Transcript

  1. Computer Integrated Design introduction

  2. current state • still documentation • want to change that • designers must become fluent

  3. 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

  4. 3D modelling 15/30

  5. 3D modelling 5

  6. 3D modelling

  7. represent and manipulate graphic and non-graphic information life cycle • brief • concept • developed detail • manufacture / construction • operation • destruction / demolition

  8. new designs • new forms • possible through use of computers • complex geometries • too difficult to construct • can’tvisualize otherwise • Mitchell Beyond the Tower: Constructing Complexity in the Digital Age Gehry

  9. 10

  10. 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

  12. does not upset the creative act use of computers

  13. computers in design • aid with sketches & ideas • develop themes / concepts • facilitate production dwgs • analyses to satisfy functional reqmnts • speed manufacturing process • control operation/maintenance 15

  14. 3 aspects of 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

  15. CAD tools are whatever designers make of them

  16. integration & automation CAD the driver • automate processes in design • automatic transfer of information • design for manufacture • DfM,DfX

  17. the construction process • 4-D CAD • CAD modelling to represent the construction process • staged

  18. user participation • involvement of clients • community involvement • presentation of alternatives • implications – environment, cost, … 20

  21. Kunsthaus Graz

  22. Kunsthaus - Graz • blob architecture - BIX media facade • non-euclidean geometry • modelling based on B-spline surface modelling • distorted sphere • pulling control points

  23. Kunsthaus - Graz • different models • for different aspects • structure, cladding, ventilation, … 25
