Abstract: In the design of metro lines, the station-yard plan plays a very important role. In view of the low efficiency and irregular format of the current station-yard plan drawing, learning from the Visio shape, the Visio program was used to create graphics, analyze graphics and transmit information between graphics and external data sources. This article proposed a method of redevelopment of Visio by using C# language, designed and developed the humancomputer interactive drawing interface based on Visio and the automatic drawing interface based on Windows-based user interface framework(WPF). The research results and the developed software have been applied to practical engineering applications. Good results have been achieved and the drawing has been improved. The efficiency and accuracy of the map provide a fast way for users to draw the station-yard plan.
