コードのサンプル
The following stand-alone script displays properties for a CAD drawing dataset:
import arcpy
# Create a describe object
#
desc = arcpy.Describe("C:/data/arch.dgn")
# Print Cad Drawing Dataset properties
#
print("%-12s %s" % ("is2D:", desc.is2D))
print("%-12s %s" % ("is3D:", desc.is3D))
print("%-12s %s" % ("isAutoCAD:", desc.isAutoCAD))
print("%-12s %s" % ("isDGN:", desc.isDGN))
