Why Model Sketching? Part 2. As a student attending Cooper Union, I vividly remember the first time I saw one of my peers “sketch” in model form. While I was well versed in sketching through drawing, and was particularly fond of diagraming concepts to develop ideas, I was surprised by this new method of allowing ideas to emerge like in a sketch, but within a three-dimensional context.  There was something seamless between idea and representation, between thinking, seeing, and how the hand dances while crafting the model. I was hooked and wanted to explore this new process.
