Multipatch Footprint

Summary

Creates polygon footprints representing the two-dimensional area of multipatch features.

Illustration

Multipatch Footprint

Usage

  • The output footprint will have the same fields as the input feature, along with the following fields:

    • Z_Min—The smallest Z value from the multipatch feature.
    • Z_Max—The largest Z value from the multipatch feature.
  • Use the Group Field parameter if a structure is comprised by multiple features that share a common identifier in the attribute table.

Syntax

MultiPatchFootprint_3d (in_feature_class, out_feature_class, {group_field})
ParameterExplanationData 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
group_field
(Optional)

The field used for combining multipatch features so that they contribute to the same footprint polygon.

Code sample

MultiPatchFootprint example 1 (Python window)

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

arcpy.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.

'''****************************************************************************
Name: MultiPatchFootprint Example
Description: Creates footprint polygons for all multipatches in a workspace.
****************************************************************************'''
import arcpy

# Set environment settings
arcpy.env.workspace = 'C:/data'
fcList = arcpy.ListFeatureClasses()
if fcList:
    for fc in fcList:
        # Determine if the feature class is a multipatch
        desc = arcpy.Describe(fc)
        if desc.shapeType is "MultiPatch":
            outPoly = "{0}_Footprint.shp".format(desc.baseName)
            #Execute MultiPatchFootprint
            arcpy.ddd.MultiPatchFootprint(fc, outPoly)
