Cluster.Elements
Returns a ClusterElementCollection which provides access to the mapping between the indices of the Cluster and the associated indices on the Geometry. This is important for clusters which contain only a subset of the components. For example the point at index 10 in the cluster might be point 456 on the geometry.
// get accessor ClusterElementCollection rtn = Cluster.Elements; |
' This example demonstrates how Cluster indices are mapped to indices of the points
' on the Geometry via the Cluster.Elements property
