In this paper, the graphic element editing commonly used in the flow chart system is designed with high-level language, and the basic method of using these graphics to form the flow chart in engineering is provided, and the application program is provided with object classes.

Flowchart is the representative of information flow, viewpoint class or partial class diagram flowing through a system. In enterprises, flowcharts are mainly used to show a process. This process can be a technological process on the production line, and it can also complete the key management process of a task. this

This paper is based on the knowledge of graphic storage and planning, and is compiled by using MFC and Visual C++ 6.0. In this drawing application, the main functions of general drawing applications are realized and some additional auxiliary functions are provided. According to the functions realized by the application program, the program can be divided into the following modules: basic graphic element planning, graphic modification, graphic element modification, auxiliary functions and graphic file storage. The rules for dividing these modules are mainly based on the relationship between functions. Similar process functions are divided into a module.

Finally, through repeated debugging, the following functions and effects are realized.

1, plan primitive

2, graphic modification and editing

3. Modification and editing of primitives
