AUTOCAD自动获取所有填充的边界并在重心处输出填充的面积数值，对于填充极多，并要根据填充的面积数值和边界节点进行编辑有很大的好处。在此基础上可以实现很多的功能（只支持2007，略修改可以自由输出面域或多段线的边界）（代码很精简，对初学者有很大好处）（操作为加载后运行“bj”和“tcmj”）-AUTOCAD automatic access to all the filling in the center of gravity of the border and fill the output area of Department values, for a lot of filler, and fill the area in accordance with values and boundary node editing is highly desirable. On this basis can achieve a lot of features (only support 2007, a little freedom to modify the domain or the output side of the border line above) (the code is very lean, there are significant benefits for beginners) (after operation for the loading operation　bj　and　tcmj )
