Intersect 3D

Summary

Computes the intersection of multipatch features to produce closed multipatches encompassing the overlapping volumes, open multipatch features from the common surface areas, or lines from the intersecting edges.

Illustration

Usage

• Exercise caution when determining the data used for this analysis. Highly detailed features may produce extremely complex geometries that could exhibit display performance issues on account of their total number of vertices and orientation.

• If one input is given, the intersection of features in that multipatch dataset will be evaluated, whereas if two were given, the intersection of features from both datasets will be determined and intersections found in only one input get ignored.

  Note:

  When using two input features, attributes from both features get concatenated in the output.

Syntax

Intersect3D_3d (in_feature_class_1, out_feature_class, {in_feature_class_2}, {output_geometry_type})

Parameter	Explanation	Data Type
in_feature_class_1	The multipatch features that will be intersected. When only one input feature layer or feature class is provided, the output will indicate the intersection of its own features.	Feature Layer
out_feature_class	The feature class that will be produced by this tool.	Feature Class
in_feature_class_2 (Optional)	The optional second multipatch feature layer or feature class to be intersected with the first.	Feature Layer
output_geometry_type (Optional)	Determines the type of intersection geometry created. SOLID —Creates a closed multipatch representing the overlapping volumes between input features. This is the default. SURFACE —Creates a multipatch surface representing shared faces between input features. LINE — Creates lines representing shared edges between input features.	String

Code sample

Intersect3D example 1 (Python window)

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

import arcpy
from arcpy import env

env.workspace = 'C:/data'
arcpy.Intersect3D_3d('inMultipatch1.shp', 'outMultipatch.shp', 
                    'inMultipatch2.shp')

Intersect3D example 2 (stand-alone script)

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