コードのサンプル
EncloseMultiPatch の例 1 (Python ウィンドウ)
次のサンプルは、Python ウィンドウでこのツールを使用する方法を示しています:
arcpy.env.workspace = 'C:/data'
arcpy.ddd.EncloseMultiPatch('unclosed_features.shp',
'enclosed_features.shp', 0.5)
EncloseMultiPatch の例 2 (スタンドアロン スクリプト)
次のサンプルは、スタンドアロン Python スクリプトでこのツールを使用する方法を示しています:
'''*********************************************************************
Name: Model Shadows For GeoVRML Models
Description: Creates a model of the shadows cast by GeoVRML models
imported to a multipatch feature class for a range of dates
and times. A range of times from the start time and end
time can also be specified by setting the EnforceTimes
Boolean to True. This sample is designed to be used in a
script tool.
