Is Closed 3D


Evaluates multipatch features to determine whether each feature completely encloses a volume of space.


  • This tool will add a new field called IsClosed that indicates whether a given feature is closed.

  • Consider using the Enclose Multipatch tool to construct closed features out of those that are not closed.
