One of thedownsides of the computer system is that it cannot transfer all the fundamentalexpects of physical models into a full geometric description.
It losses the nuance in the form during thetransfer procedure from the hand-built models. In ‘Digital SurfaceRepresentation and Constructability of Gehry’s Architecture’ (1995), Sheldennoted: “…the geometric controls and operations by which paper surfaces areconstructed in digital are radically different than – and in many ways impoverishedcompared to – the flexibility and intuitiveness of direct materialmanipulation.” The process of digital modeling, thus, is not directly andautomatically achieving. Due to this, Gehry’s studio stressed the physical artifactand material-based modeling as their principle of the design approach. Thedesign process depended on the tactile and verification Paper was mostly usedin the models’ surfaces to present the constructability of similarity materialin real life construction like a metal sheet or plywood. Then the digitalsurfacing software combined with the scanner was used to better understand thephysical model and transfer it into mathematical points in digital.
Another benefitof using digital technology is database aspect, which provides better collaborationbetween Gehry’s studio and subcontractors. The idea of using the digitaldatabase for construction was first used in the aircraft and automobile design,which was developed by Dassaults Aviation, called CATIA. CATIA was borrowed andcombined with Gehry’s architectural document for their surface modelingcapacity. (Shelden, 1995:110) The program emphasized the paperlessdocumentation and subcontractor collaboration. It allows specialists andsubcontractors have a better understanding of design construction in the earlyphase of the project, reduce the risk of cost corrections and changes. Thus, itmade Gehry’s and his studio become a leader in architectural program developer.
Last but least,another benefit of the digital model is that it provides a possibility toforecast the constructability of the design by adding the analytical andparametric tools to define the surface and calculate the reinforcement aspectof the form. ‘Regularisation’ is used to identify the forms of the buildingfrom the given geometric characteristics under the assistance of a computer.Only with the help of analytical computer program, the aesthetical and complexsurfaces or geometries, which are common in Gehry’s designs, can bediscoverable and predictable.
