||BridgeCAD is an integrated large capacity UNlX workstation modeling software for visualising,analysing, dimensioning and drawing bridge super- and substructures. It is a part of theCityCAD infrastructure design system and it's database is integrated in the CityCADs relationaldatabase. BridgeCAD is specialized in modeling concrete girder bridges.In the BridgeCAD the modeling procedure has been split into several well defined parts andrelated programs. The core of the BridgeCAD consists of the BCMOD, an interactive graphicsprogram, which is used for constructing the three-dimensional model of the bridgesuperstructure. Other program parts are abutment modeling, bridge visualization, structuralanalysis, dimensioning and drawing modules.
