CAD system which designs 3-D models

摘要

The computer aided design (CAD) system for interactively designing three dimensional models for architectural projects operates on a client-server model in a distributed network, such as the Internet. The server first elicits general project information from the client, then prompts the client for detail project information through a scripting process, preferably using voice recognition software. As components are added to the project, an expert knowledge system reviews the model against heuristic rules and for conflicts with component manufacturer specifications and building codes. The server then creates a 3-D model. The client can take a virtual walk through of the model, making any desired revisions. Upon completion, the server provides the client with a 3-D CAD model, two dimensional CAD drawings in plan, elevation and section as desired, and completed construction schedule specifications, budget, and other documentation.
