Optimization can also be disabled in the absence of a grouping field if the desired output is to union all overlapping features into a single multipatch. Disabling optimization can increase the tool's performance if a grouping field has been specified. When optimization is enabled, the tool attempts to automatically subset theįeatures into groups by analyzing the bounding box for each feature. Rather than comparing a feature against all features, it is only compared against those that participate in its group. This can significantly improve performance by reducing the number of times the tool must iterate through the dataset. This process occurs iteratively until all multipatch features in the feature class have been processed.Ī grouping field can be used to identify features to be unioned, such as when the multipatches represent building parts in a city where multiple features represent one building. Multipatch features encompassing overlapping volumes are combined by intersecting the shells of the features and removing redundant interior portions. ![]() 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. Closed multipatch geometry is required for this analysis. ![]()
