用法
- 
多面体要素中高程值的范围归因于输出要素类中的 Z_MIN 和 Z_MAX 字段。
 
语法
MultipatchFootprint_3d (in_feature_class, out_feature_class)
| 参数 | 说明 | 数据类型 | 
in_feature_class  | 
 将要生成覆盖区的多面体要素。  | Feature Layer | 
out_feature_class  | 
 生成的覆盖区面要素类。  | Feature Class | 
代码示例
MultipatchFootprint 示例 1(Python 窗口)
The following sample demonstrates the use of this tool in the Python window:
import arcpy
from arcpy import env
arcpy.CheckOutExtension("3D")
env.workspace = "C:/data"
arcpy.MultiPatchFootprint_3d("multipatch.shp","multipatch_footprint.shp")
MultipatchFootprint 示例 2(独立脚本)
The following sample demonstrates the use of this tool in a stand-alone Python script:
'''****************************************************************************
Name: MultiPatchFootprint Example
Description: Creates footprint polygons for all multipatches in a workspace.
****************************************************************************'''
import arcpy
import exceptions, sys, traceback
from arcpy import env
try:
    arcpy.CheckOutExtension('3D')
    # Set environment settings
    env.workspace = 'C:/data'
    fcList = arcpy.ListFeatureClasses()
    if fcList:
        for fc in fcList:
            # Determine if the feature class is a multipatch
            desc = arcpy.Describe(fc)
            if desc.shapeType is "MultiPatch":
                outPoly = "{0}_Footprint.shp".format(desc.baseName)
                #Execute MultiPatchFootprint
                arcpy.ddd.MultiPatchFootprint(fc, outPoly)
    arcpy.CheckInExtension('3D')
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)
