Editing 3D multipatch features

Multipatch features can be used for different reasons, for example, to enhance 3D realistic symbology of a feature. Multipatch features can be edited in ArcScene, ArcGlobe, and ArcMap, just like all other feature types. However, as multipatch features are usually three-dimensional, and the ArcMap editing environment is two-dimensional, there are some limitations with the tools and functions available in that environment. Since ArcScene and ArcGlobe are three-dimensional environments, there are more editing options available for multipatch features, such as Replace with model and the Insert construction tool.

The 3D editing environment for multipatch editing focuses on whole feature management. That is, you can move, rotate, scale, delete, insert, replace, and copy multipatch features, as well as define and populate attributes for the features. Multipatch features can be created by converting 3D symbology to multipatch features or through 3D geoprocessing tools such as Layer 3D To Feature Class. You can also write ArcObjects code for generating complex multipatch geometries.

Supported editing actions for multipatches

Many editing actions are useful for multipatch geometries and are available for use with multipatch features. The list below represents common editing tasks for multipatch features:

Unsupported editing actions for multipatches

Some editing actions are not appropriate for multipatch geometries and have been made unavailable for use with multipatch features. The list below contains some of the editing actions that are not available:

TipTip:
Know your data. Although an extruded polygon may look like a multipatch solid, it will behave differently when editing in 3D. For example, scaling an extruded polygon will only scale in the x- and y-axes (2D). You must adjust the extrusion height (z-value) manually using the Layer Properties dialog box for that feature.
