Summary

Eliminates portions of multipatch features in a target feature class that overlap with enclosed volumes of multipatch features in the subtraction feature class.

Usage

  • Closed multipatch geometry is required for this analysis. The Is Closed 3D tool can be used to determine if a multipatch feature class contains closed features, and the Enclose Multipatch tool can be used to eliminate gaps in multipatch features.

  • Input features that are fully enclosed by a subtract feature will be completely removed in the output

  • This tool's execution can be very time consuming, and care should be taken when selecting input datasets.

  • The output features will not have any of the attributes of the input features. If necessary, a spatial join to the source features or a relationship class to the optional output table can be constructed to map attributes from the input features to the output dataset.

Parameters

LabelExplanationData Type
Input Features

The multipatch features that will have its features removed by the subtrahend features.

Feature Layer
Subtract Features

The multipatch features that will be subtracted from the input.

Feature Layer
Output Feature Class

The output multipatch feature class that will contain the resulting features.

Feature Class
Output Table
(Optional)

An optional table that stores information about the relationship between the input features and the difference output. The following fields are present in this table:

  • Output_ID—The ID of the output feature.
  • Minuend_ID—The ID of the input feature.
  • Subtrahend—The ID of the subtract feature.
