Interpolate Polygon To Multipatch (3D Analyst)

Resumen

Creates surface-conforming multipatch features from a polygon feature class and a raster, terrain, or TIN surface.

The attributes from the input features are copied to the output. Planimetric and surface area are calculated for each feature and added as attribution to the output.

Sintaxis

InterpolatePolyToPatch_3d (in_surface, in_feature_class, out_feature_class, {max_strip_size}, {z_factor}, {area_field}, {surface_area_field}, {pyramid_level_resolution})
ParámetroExplicaciónTipo de datos
in_surface

The input triangulated irregular network (TIN) or terrain dataset surface.

Terrain Layer; TIN Layer
in_feature_class

The input polygon feature class.

Feature Layer
out_feature_class

The output multipatch feature class.

Feature Class
max_strip_size
(Opcional)

Controls the maximum number of points used to create an individual triangle strip. Note that each multipatch is usually composed of multiple strips. The default value is 1,024.

Long
z_factor
(Opcional)

The factor by which elevation values will be multiplied. This is typically used to convert Z linear units that match those of the XY linear units. The default is 1, which leaves elevation values unchanged.

Double
area_field
(Opcional)

The name of the output field containing the planimetric, or 2D, area of the resulting multipatches.

String
surface_area_field
(Opcional)

The name of the output field containing the 3D area of the resulting multipatches. This area takes the surface undulations into consideration and is always larger than the planimetric area unless the surface is flat, in which case, the two are equal.

String
pyramid_level_resolution
(Opcional)

The z-tolerance or window size resolution of the terrain pyramid level that will be used by this tool. The default is 0, or full resolution.

Double

InterpolatePolygonToMultipatch 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.InterpolatePolyToPatch_3d("sample.gdb/featuredataset/terrain", "polygon.shp", "out_multipatch.shp", 1024, 1, "Area", "SArea", 5)
InterpolatePolygonToMultipatch example 2 (stand-alone script)

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

'''****************************************************************************
Name: InterpolatePolyToPatch Example
Description: This script demonstrates how to use the 
             InterpolatePolyToPatch tool.
****************************************************************************'''

# Import system modules
import arcpy
from arcpy import env

arcpy.CheckOutExtension("3D")

# Set environment settings
env.workspace = "C:/data"

# Set Local Variables
inTerrain = "sample.gdb/featuredataset/terrain"
inPoly = "polygon.shp"
outMP = arcpy.CreateUniqueName("out_multipatch.shp")

#Execute InterpolatePolyToPatch
arcpy.InterpolatePolyToPatch_3d(inTerrain, inPoly, outMP, 1024, 1, "Area", "SArea", 5)
