Input Multipatch Features
| The multipatch features that will be used to construct closed multipatches. | Feature Layer |
Output Multipatch Feature Class
| The output closed multipatch features. | Feature Class |
Grid Size
(Optional) | The resolution that will be used to construct the closed multipatch features. This value is defined using the linear units of the input feature's spatial reference. | Double |
Summary
Creates closed multipatch features from open multipatch features.
Usage
This tool is used for multipatch features that have an opening along the lower portions of the geometry. The enclosed output will drape along the input feature and obscure any overhangs that may be present in the input feature.
All multipatch features will be evaluated to determine those that are closed. Existing closed features will be copied to the output multipatch with no modification. The Is Closed 3D tool can be used to quickly determine whether any unclosed multipatch features exist in the input feature class.
Textures and colors from the input multipatch features will not be preserved in the output.
Parameters
arcpy.ddd.EncloseMultiPatch(in_features, out_feature_class, {grid_size})| Name | Explanation | Data Type |
in_features | The multipatch features that will be used to construct closed multipatches. | Feature Layer |
out_feature_class | The output closed multipatch features. | Feature Class |
grid_size (Optional) | The resolution that will be used to construct the closed multipatch features. This value is defined using the linear units of the input feature's spatial reference. | Double |
Code sample
The following sample demonstrates the use of this tool in the Python window.
arcpy.env.workspace = 'C:/data'

Name: Model Shadows For GeoVRML Models
Description: Creates a model of the shadows cast by GeoVRML models
imported to a multipatch feature class for a range of dates
and times. A range of times from the start time and end
time can also be specified by setting the EnforceTimes
Boolean to True. This sample is designed to be used in a
script tool.
