|Architects don’t build without modeling. They create “blueprints,” produce renderings, and build 3D models. But while these planning tools may resemble the actual building in shape, there is no resemblance in size or materials. As a result, except in the case of manufactured or modular buildings, the finished product will be the first time that real building materials have come together in exactly that configuration. That is one of the reason that architecture tends to be conservative in its rate of change. Without real-world testing, big change is risky.
