Uses startFaceIndex and finds all connected face indexes up to unwelded or naked edges. If treatNonmanifoldLikeUnwelded is true then non-manifold edges will be considered as unwelded or naked

public int[] GetConnectedFacesToEdges(
	int startFaceIndex,
	bool treatNonmanifoldLikeUnwelded
)

VB

Public Function GetConnectedFacesToEdges ( 
	startFaceIndex As Integer,
	treatNonmanifoldLikeUnwelded As Boolean
) As Integer()

startFaceIndex

Type: System.Int32
Initial face index

treatNonmanifoldLikeUnwelded

Type: System.Boolean
True means non-manifold edges will be handled like unwelded edges, False means they aren't considered

Type: Int32[]
Array of connected face indexes
