The Architecture, Engineering, and Construction (AEC) Industry today is in a state of transition from purely 2D drawings, to purely 3D models. The attraction of full 3D model representation (i.e. BIM) is more complete documentation, more robust conflict resolution, and a general expansion of the “constructable” design space. Yet, 2D drawings remain an essential tool. From quick napkin sketches that close a real estate deal, to detailed drawings referenced by on site workers, 2D drawings can often communicate far more information in much shorter time, than large 3d data sets.

In this talk, we ask: Why is this? Are there general principles associated with the mechanics of representation that will allow us to communicate our intent more effectively? By studying established theories from the Philosophy of Science and modern User Experience and Interaction Design, we will propose three modes of representation that can be used to create better drawings, better models, and better tools.
