Multipatch Footprint (3D Analyst)

Summary

Creates polygon footprints representing the two-dimensional area occupied by a multipatch feature class.

Illustration

Usage

• The range of elevation values in the multipatch feature would be attributed to the Z_MIN and Z_MAX fields in the output feature class.

Syntax

MultipatchFootprint_3d (in_feature_class, out_feature_class)

Parameter	Explanation	Data Type
in_feature_class	The multipatch feature whose footprint will be generated.	Feature Layer
out_feature_class	The resulting footprint polygon feature class.	Feature Class

Code Sample

MultipatchFootprint example 1 (Python window)

The following sample demonstrates the use of this tool in the Python window:

import arcpy
from arcpy import env

arcpy.CheckOutExtension("3D")
env.workspace = "C:/data"
arcpy.MultiPatchFootprint_3d("multipatch.shp","multipatch_footprint.shp")

MultipatchFootprint example 2 (stand-alone script)

The following sample demonstrates the use of this tool in a stand-alone Python script:

    if fcList:
        for fc in fcList:

            desc = arcpy.Describe(fc)
            if desc.shapeType is "MultiPatch":
                outPoly = "{0}_Footprint.shp".format(desc.baseName)

    arcpy.CheckInExtension('3D')
except arcpy.ExecuteError:
    print arcpy.GetMessages()
except:
    # Get the traceback object
    tb = sys.exc_info()[2]
    tbinfo = traceback.format_tb(tb)[0]
    # Concatenate error information into message string
    pymsg = 'PYTHON ERRORS:\nTraceback info:\n{0}\nError Info:\n{1}'\
          .format(tbinfo, str(sys.exc_info()[1]))
    msgs = 'ArcPy ERRORS:\n {0}\n'.format(arcpy.GetMessages(2))
    # Return python error messages for script tool or Python Window
    arcpy.AddError(pymsg)
    arcpy.AddError(msgs)
