Operation method for drawing quadrangle according to statistical data in CAD

The invention discloses an operation method for drawing a quadrangle according to statistical data in CAD (computer-aided design). The operation method comprises the steps of compiling a function to form a functional module, determining a position and selecting data to realize drawing of any quadrangle. A new function module is formed by writing functions, drawing of any quadrangle and diagonals thereof is rapidly and accurately completed according to statistical data, the working efficiency of designers is improved, meanwhile, high drawing precision is guaranteed, and the graph drawing problem of a large number of non-standard quadrangles with different data is effectively solved. 本发明公开了一种在CAD中根据统计数据绘制四边形的操作方法，包括编写函数形成功能模块，确定位置并选择数据实现任意四边形的绘制。通过编写函数形成新的功能模块，根据统计数据快速且精确的完成任意四边形及其对角线的绘制，提升设计人员的工作效率，同时保证较高的绘制精度，有效解决大量非标准、数据不相同的四边形的图形绘制问题。
