摘　　要：论述了通过继承DrawJig类的所有方法、过程和事件,重载Sampler和WorldDraw函数,实现用户定制CAD互动命令的步骤和方法。详细介绍了动态坐标标注实例,通过DrawJig类控制拖动序列接受用户的选定坐标点,从而确定坐标标注各要素的标注位置,最后采用AddEntity函数向CAD数据库添加实体对象的方法实现了数字化成图软件中的动态标注功能。By inheriting all the methods,processes and events of DrawJig,heavy loading Sampler and WorldDraw,the user customization of CAD interactive command＇s step and method is accomplished.Take dynamic coordinates marked as an example.The process of it is firstly through DrawJig class control to accept user to drag the selected sequence coordinates of points in order to determine the elements of the mark coordinates marked position,and finally using the method of adopting AddEntity function to append Entity object to CAD database to achieve the function dynamic marking in digital mapping software.
