An Architectural Modeler and Its Incorporation into the Design 4D program

Abstract

A common user complaint about computer-assisted design (CAD) programs is that the software is marketed as a design tool but does not help significantly in the building design process, which is a decision making activity. Design 4D is an architectural modeler that user 3D geometry and a seamless database manager to address the needs of Schematic Design. The user interface of Design 4D provides the architect with several new capabilities: to sketch in perspective, to alternate between two- and three-dimensional views, and to use a varied set of layout tools that work equally well when oriented to any axis. This manuscript gives an overview of the three-dimensional interface, the display manipulation within Design 4D, and the modeling implementation developed for this study. Also examined are the geometric database and additional modeling data structures used by Design 4D. (kr)
