A STUDY OF FACILITY MANAGEMENT SYSTEM IN THE COMPUTER AIDED DESIGN USING 3 DIMENSIONAL DATA BASE

摘要

This paper presents a new development of Facility Management System as applied to CAD (Computer Aided Design) using 3D (3 Dimensional) Data Base supported by a R.D.B (Relational Data Base) system in the environment of digital mapping. This system consists of MAPCAD (a digital mapping system developed by PASCO) and an architectural CAD system, both based on AutoCAD graphic platform. The relational data base system being utilized is R:BASE. In this paper, the authors describe the concepts of 3D drawing description and the linkage of relational data base (i.e. R:BASE) to this 3D drawing data via AutoCAD attributes. Although the present data base system is PC-based system, it will be further extended as Facility Management 3D- Data Base System on Engineering Work Stations. Then this system will be applied in various urban planning activities such as in amenity planning, ecological planning, economical planning and landscape design, etc..
