用法
语法

subtype_code |
子类型的唯一默认值。 | Long |
代码示例
设置默认子类型示例(Python 窗口)
以下 Python 窗口脚本演示了如何在立即模式下使用 SetDefaultSubtype 函数。
import arcpy from arcpy import env env.workspace = "C:/data/Montgomery.gdb" arcpy.SetDefaultSubtype_management("water/fittings", 5)
设置默认子类型示例 2(独立脚本)
以下独立脚本演示了如何在将子类型添加到字段的工作流中使用 SetDefaultSubtype 函数。
#Name: ManageSubtypes.py # Purpose: Create a subtype definition # Author: ESRI # Import system modules import arcpy from arcpy import env try: # Set the workspace (to avoid having to type in the full path to the data every time) env.workspace = "C:/data/Montgomery.gdb" # Set local parameters inFeatures = "water/fittings" # Process: Set Subtype Field... arcpy.SetSubtypeField_management(inFeatures, "TYPECODE") # Process: Add Subtypes... # Store all the suptype values in a dictionary with the subtype code as the "key" and the # subtype description as the "value" (stypeDict[code]) stypeDict = {"0": "Unknown", "1": "Bend", "2": "Cap", "3": "Cross", "4": "Coupling",\ "5": "Expansion joint", "6": "Offset", "7":"Plug", "8": "Reducer",\ "9": "Saddle", "10": "Sleeve", "11": "Tap", "12": "Tee", "13": "Weld", "14": "Riser"} # use a for loop to cycle through the dictionary for code in stypeDict: arcpy.AddSubtype_management(inFeatures, code, stypeDict[code]) # Process: Set Default Subtype... arcpy.SetDefaultSubtype_management(inFeatures, "4") except Exception, e: # If an error occurred, print line number and error message import traceback, sys tb = sys.exc_info()[2] print "Line %i" % tb.tb_lineno print e.message
