Interior design focuses on the creation of environments for a variety of user groups.
Before the existence of software that allows the modeling of three-dimensional objects and spaces, designers had no means of predicting the actual physical, functional, and aesthetic impact of their proposals. As can be imagined, having to postpone evaluation until construction is expensive in time, money, and materials. By definition, design students lack a professional's experiential background. In an ideal pedagogical universe, students would be able to test their ideas, building and evaluating them as environmental constructs.
