Modify a 3D object feature class

A 3D object feature class stores and manages features in a geodatabase using a defined geographic location with a referenced 3D geometry mesh. The referenced geometry of a feature can be stored in multiple formats. You can modify the 3D object feature class by managing that list of storage formats. You can also remove all referenced formats and convert the 3D object feature class to a multipatch feature class.

Add storage formats to a 3D object feature class

Add one or more storage formats to a 3D object feature class to provide more options for direct editing and replacement of feature geometries using third-party applications and importing 3D model files. This increases the storage size of the data, because every feature will be stored in every chosen file format.

1. On the Analysis tab in the Geoprocessing group, click Tools .

   The Geoprocessing pane appears.

2. Click the Toolboxes tab and browse to Data Management > 3D Objects, and double-click the Add 3D Formats to Multipatch geoprocessing tool.

   The Add 3D Formats to Multipatch tool opens in the Geoprocessing pane.

3. Click the Input Features drop-down arrow and select the multipatch feature class, or click browse to browse to its location.
4. In the 3D Formats to Add section, check the boxes next to the formats you want the layer to support.

   Formats that are already included in the layer are not listed.

5. Click Run .

The 3D object feature class is ready to store models in the additional formats for each feature.

Remove storage formats from a 3D object feature class

Remove one or more storage formats from a 3D object feature class to reduce the number of models that are stored and maintained for the layer. This reduces storage space and can improve interactive editing performance.

1. Open the Remove 3D Formats From Multipatch geoprocessing tool. For the Input Features parameter, select the 3D object feature class or browse to it.
2. In the 3D Formats to Remove section, check the boxes next to the supported formats you want to remove for the layer and run the tool.

   Only formats that are currently included in the layer are listed.

The 3D models in the specified formats are removed for each 3D object feature.

Convert a 3D object feature class to a multipatch feature class

Removing all the storage formats from a 3D object feature class also removes all the related tables and relationship classes for the layer. This converts the 3D object feature class to a standard multipatch feature class. This can be useful if you need to use the content in earlier versions of ArcGIS Pro that don't support 3D object feature classes.

1. On the Analysis tab in the Geoprocessing group, click Tools .

   The Geoprocessing pane appears.

2. Click the Toolboxes tab and browse to Data Management > 3D Objects, and double-click the Remove 3D Formats From Multipatch geoprocessing tool.

   The Remove 3D Formats From Multipatch tool opens in the Geoprocessing pane.

3. Open the Remove 3D Formats From Multipatch geoprocessing tool. For the Input Features parameter, select the 3D object feature class or browse to it.
4. In the 3D Formats to Remove section, click Select All to select all the currently supported formats and run the tool.

   Every format must be removed to convert the data to a multipatch feature class.

The schema of the feature class is updated to remove all related tables and models. The feature class becomes a multipatch feature class. The features in the feature class are preserved.
