Abstract: In order to improve line design′s efficiency and ensure design′s immediacy and accuracy, combined the scenarios building technology based on CAD and GIS, the CAD and GIS design scene′s linkage and switch were formed by using factory pattern based on reflection mechanism of .NET technology. Through the double-scene linkage technology, line path and flat and sectional diagram′s linkage and rowing tower′s linkage were accomplished. The technology makes the rowing towers and wiring more intuitive and the flat and section drawing more scientific. The design of CAD and GIS integrated into the design of overhead transmission line makes the design of transmission line easier, which meet the need of building strong smart grid.
