说明：  本程序为CAD自定义图例代码，地质制图中经常需要自定义图例，软件自带图例经常不能满足实际工作的需要，CAD在填充时也是如此，本程序做了上百种地质工作中经常遇到的图例，放到根目录直接可以使用，与前面上传的代码共同配合使用，放在根目录下
(The procedures for the CAD custom legend code, geological mapping often need to customize legend, software own legend often can not meet the need of practical work, CAD in filling is also so, this procedure done hundreds of geological work frequently met in legend, in the root directory can be used directly, and front upload code with common use, in the root directory)
