3D 图层转要素类 (3D Analyst)

摘要

将定义了 3D 属性的要素层导出到多面体要素类。

用法

语法

Layer3DToFeatureClass_3d (in_feature_layer, out_feature_class, {group_field})
参数说明数据类型
in_feature_layer

定义了 3D 属性的输入要素图层。

Feature Layer
out_feature_class

输出多面体要素类。

Feature Class
group_field
(可选)

输入要素类中标识将组合为同一多面体要素的要素的字段。生成的属性将被设置为其中一个输入记录。

Field

代码示例

Layer3DToFeatureClass 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.Layer3DToFeatureClass_3d("Points_3D.lyr", "Test.gdb/trees")
Layer3DToFeatureClass 示例 2(独立脚本)

The following sample demonstrates the use of this tool in a stand-alone Python script:

'''****************************************************************************
Name: Layer3DToFeatureClass Example
Description: This script demonstrates how to use the 
             Layer3DToFeatureClass tool to create multipatches from all
             layers in a target workspace. The layer files are assumed to have
             been saved wtih 3D rendering from ArcScene.
****************************************************************************'''
# Import system modules
import arcpy
from arcpy import env
import exceptions, sys, traceback

try:
    # Obtain a license for the ArcGIS 3D Analyst extension
    arcpy.CheckOutExtension("3D")
    
    # Set environment settings
    env.workspace = "C:/data"
    
    # Use the ListFiles method to identify all layer files in workspace
    if arcpy.ListFiles("*.lyr"):
        for lyrFile in arcpy.ListFiles("*.lyr"):
            # Set Local Variables
            outFC = "Test.gdb/{0}".format(lyrFile[:-4]) #Strips '.lyr' from name
            #Execute Layer3DToFeatureClass
            arcpy.Layer3DToFeatureClass_3d(file, outFC)
    else:
        "There are no layer files in {0}.".format(env.workspace)

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)
