ArcMap

是否为闭合 3D

摘要

评估多面体要素以确定是否每个要素为完全封闭的空间体。

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给定要素已闭合。

  • 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

派生输出

名称说明数据类型
output_feature_class

代码示例

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。

'''****************************************************************************
Name: IsClosed3D Example
Description: This script demonstrates how to use the 
             IsClosed3D tool on all multipatches in a target workspace.
****************************************************************************'''
# Import system modules
import arcpy
import exceptions, sys, traceback
from arcpy import env

try:
    # Obtain a license for the ArcGIS 3D Analyst extension
    arcpy.CheckOutExtension('3D')
    # Set environment settings
    env.workspace = 'C:/data'
    # Set Local Variables
    for fc in arcpy.ListFeatureClasses(): # list features in workspace
        # Determine which features are multipatches
        if arcpy.Describe(fc).shapeType == 'MultiPatch':
            # Execute Is Closed 3D
            arcpy.IsClosed3D_3d(fc)
    

except arcpy.ExecuteError:
    print arcpy.GetMessages()
except:
    # Get the traceback object
    tb = sys.exc_info()[2]
    tbinfo = traceback.format_tb(tb)[0]
    # Concatenate error information into message string
    pymsg = 'PYTHON ERRORS:\nTraceback info:\n{0}\nError Info:\n{1}'\
          .format(tbinfo, str(sys.exc_info()[1]))
    msgs = 'ArcPy ERRORS:\n {0}\n'.format(arcpy.GetMessages(2))
    # Return python error messages for script tool or Python Window
    arcpy.AddError(pymsg)
    arcpy.AddError(msgs)
