描述
Splits features for any number of polyline or polygon target feature classes using the cutting features and inserts points on the cutting feature.
使用方法
Cutting features must have at least one feature selected.
Target features will be divided into multiple features at any point where they intersect the source features.
Source features will have new vertices added at every point where they intersect the target features.

代码示例
SplitFeatures example (stand-alone script)
This script demonstrates how to use SplitFeatures.
# Name: SplitFeatures_Example.py
# Description: Split road features by AOI polygons
# Requirements: ArcGIS Defense Mapping solution
# Import the Arcpy module
import arcpy
# Check out Defense Mapping extension
arcpy.CheckOutExtension('defense')
# Set up the gp environment
arcpy.env.overwriteOutput = 1
arcpy.env.workspace = r"C:\Data\MGCP_TRD4.gdb"
arcpy.env.scratchWorkspace = r"C:\Data\SplitFeatures.gdb"
# Declare paths to AOI features and polyline features
AOIFeatures = r"C:\Program Files (x86)\ArcGIS\EsriDefenseMapping\Desktop10.2\ReferenceData\MapIndex.mdb\MapIndex\TLM50_Index"
polylineFeautres = r"C:\Data\MGCP_TRD4.gdb\MGCP\RoadL"
# Create feature layers of the AOI
arcpy.management.MakeFeatureLayer(AOIFeatures, "AOIFeatures")
# Select specific AOIs
selection = "NRN = 'E732X57714'"
arcpy.management.SelectLayerByAttribute("AOIFeatures", "NEW_SELECTION", selection)
# Execute Split Features tool
arcpy.defense.SplitFeatures("AOIFeatures", polylineFeautres, "USE_TARGET_Z")
