Analyzes a number of entities and returns a closed loop of points starting from the entity at startIndex. You can provide an array of 100 entities an get a 3D loop of a square made up of 4 lines. Entities connection is checked using chordalError parameter, if the end points of two entities are farther of this value they will not be connected.
