Civil 3D 特性集
特性集帮助文档的链接
这部分功能是从AutoCAD Architecture中继承来的，
有的朋友可能没有使用过AutoCAD Architecture，
不知其为何物，
这部分的API及样例在Civil 3d的开发文档中找不到，
但在AutoCAD Architecture的安装位置可以找到相关的样例代码，
这部分的功能比较简单，
为了查找样例单独下载安装AutoCAD Architecture过于费事，
所以我将样例中的代码复制到此，
便于有需求的朋友学习。
样例中的全部代码都在这一个cs文件中：
除了需要引用autocad的库文件外，
还需Architecture的两个文件，
如果安装了Civil 3D，
这两个问价可以在下面截图的类似位置找到。
运行样例中的命令CreatePropertySetDef
即可创建相应的特性集定义：
至于其他命令，
可以自行研究，
不再一一展示。
