arcgis arcmap使用 Python 加载 CAD 数据

可以使用 Python 脚本将 CAD 数据加载到地理数据库中。此 Python 实例演示如何使用"合并"工具将多个 CAD 工程图中的折线加载到单个要素类中。

# Name: ImportCADandMerge.py

# Description: Imports and merges polylines from one workspace into a single feature class

 

# Import system modules

import arcpy

from arcpy import env

 

env.workspace = "c:/data/columbia"

 

# Create a value table that will hold the input feature classes for Merge

vTab = arcpy.ValueTable()

 

# Step through each dataset in the list

for fd in arcpy.ListDatasets("*", "CAD"):

layername = fd + "_Layer"

# Select only the Polyine features on the drawing layer b-railroad

arcpy.MakeFeatureLayer_management(fd + "/Polyline", layername, ""Layer" = 'B-RAILROAD'")

vTab.addRow(layername)

 

# Merge the CAD features into one feature class

arcpy.Merge_management(vTab, "c:/data/columbia/Columbia.gdb/Railroads")
