The advent of Building Information Modelling (BIM) has opened a whole new range of possibilities for three-dimensional digital design renderings. Not so long ago, when we wanted to share a new building or renovation design concept with our clients (and often their clients), the options were limited. We could either provide a hand sketch or three-dimensional physical building model, using clay, paper, foamcore, wood or other materials. The result was often beautiful and effective for sharing the project vision. But it was also time consuming, static and, relatively speaking, a costly added expense. These realities limited the use of these methodologies.
