But these methods are limited in the size of the models they can produce, and they require expensive materials. So at School of Architecture at the University of Waterloo, we have been working with computer numerical control (CNC) milling to produce architectural models. We have demonstrated the utility of CNC machining by producing a 1:33 scale model of a curvilinear, precast-concrete structure for the Ballingdon Bridge in Suffolk County, England.</p><p style='text-align: right'><a href=http://www.ArchitectureWeek.com/2006/0816/tools_1-1.html><img src=http://www.ArchitectureWeek.com/images/continue.gif width=96 height=22 border=0 alt=Continue...></a></p></td></tr></table>");
