摘要
评估多面体要素以确定是否每个要素完全封闭空间体积。
用法
此工具将添加一个名为 IsClosed 的新字段，该字段用来指示是否已闭合给定要素。
考虑使用封闭多面体工具来从未闭合要素构造闭合要素。
语法
IsClosed3D_3d (in_feature_class)
| 参数 | 说明 | 数据类型 |
in_feature_class | 要测试的多面体要素。 | Feature Layer |
代码实例
IsClosed 示例 1（Python 窗口）
下面的示例演示了如何在 Python 窗口中使用此工具。
import arcpy
from arcpy import env
env.workspace = 'C:/data'
arcpy.IsClosed3D_3d('sample_multipatch.shp')
IsClosed 示例 2（独立脚本）
下面的示例演示了如何在独立 Python 脚本中使用此工具。

IsClosed3D tool on all multipatches in a target workspace.
