This paper presents a new model of the National Building Standard Design application which called design object oriented application of standard design by studding the feature and recombined the element of the Standard Design. We construct a platform of Standard Design Application Service in SAAS model to provide more fast and comprehensive service for engineers.

This paper describes the 3D Architectural Design Software Support System Platform.This platform goes beyond traditional CAD graphics technology based on geometrical primitives.It constructs building models of parametric building members following the logic of architectural design, generates plans, elevations, sections and real-time 3D view by computer analysis, and then implements automatic/manual drawing arrangement, image rendering and animation base on former results.
