Abstract


The issues about the integral application of computer aided design (CAD), geographical information system (GIS) and virtual reality (VR) technologies in engineering domain were discussed in this paper. The methods of applying CAD and GIS, GIS and VR, CAD and VR as integration on the fundamental platform of the common engineering software AutoCAD were offered in this paper: (1) Integral application of CAD and GIS: The general GIS function of AutoCAD files has been realized with the technologies of ObjectARX and database. Furthermore, the shapefile structures of ESRI Inc were analyzed thoroughly. The transformation from DWG and DXF files to shapefile and the automatic connection between the figural data and characteristic data were realized. (2) Integral application of GIS and VR: Three-dimensional simulation module SiteBuilder3D that is customized by MultiGen-Paradigm Inc for the users of ArcView is introduced, which helped to realized the settlement of making GIS planar data three-dimensional visualization. (3) Integral application of CAD and VR: With development tools of ObjectARX, Openflight API and Vega Prime API, Openflight files were written directly in AutoCAD environment and 3D View was also launched directly in AutoCAD environment. The innovation of this paper is embodied as below: (1) The author realizes the fact of software application in engineering domain, and advances carrying out GIS and VR application in AutoCAD environment. (2) It was the first for the author to introduce the three-dimensional simulation module SiteBuilder3D, and to make the integral application of GIS and VR possible. (3) It was also the first for the author to adopt development tools of Openflight API and Vega Prime API, and to make the integral application of CAD and VR possible. The production and conclusion of this paper is significant. Today, with the rapid development of computer science, the production of this paper offers the best solution of integral application of CAD, GIS and VR technology in engineering domain. It can be applied in city layout, transportation GIS, road design etc.
