%X As they design, plan, and execute AEC projects, engineers today construct task-specific geometric views based on information contained in other engineers' geometric views. Traditionally, engineers have constructed these views manually, using pencils and more recently CAD. Manually constructing views is often difficult, time-consuming, and error-prone. Newer approaches develop central project models that predetermine all potential views for a project or for an entire industry; but these approaches are proving difficult to implement due to the multi-disciplinary, constructive, iterative, and unique nature of AEC projects. Current project modeling approaches lack simple formal methods that engineers can use to specify the automatic construction of a new dependent geometric view from information in one or many source geometric views. This research formalizes reusable reasoning modules, called geometric Perspectors, which engineers can use to automatically construct a task-specific geometric engineering view, called a geometric Perspective, from other Perspectives. This paper presents engineering test cases from the design and construction of the Walt Disney Concert Hall to motivate and retrospectively validate this approach. Through implementation of a prototype, the paper gives empirical evidence that engineers can select from a potentially small number of predefined, reusable Perspectors and easily compose them into a directed acyclic graph to construct useful dependent geometric views more quickly and accurately than current practice and theory allows. Perspectors may enable engineers from multiple disciplines to engage in novel automated yet integrated design and analysis by easily yet formally constructing and integrating Perspectives from other Perspectives.
