An automated system and method is provided for configuring an object (e.g., a room). In accordance with a preferred embodiment, configuration is facilitated through the use of layering functionality and frame-based inferences to evaluate stored knowledge of object attributes. The frame-based inferences may be supplemented by a rules-based inference system. In accordance with a preferred embodiment of the invention, a graphics-based user interface may be used to permit interactive configuration using two-dimensional and three-dimensional models of the object, and incorporating engineering specifications, as well as functional and physical attributes.
