If the groups on the plane are not deleted, they will remain in the 3D view as "New" groups but will be unassigned to a plane. The SetAllNewGroupsToPlane function can be used to assign these groups to a different plane.

public void DeletePlane(
	int i1,
	int i2
)

Public Sub DeletePlane ( 
	i1 As Integer,
	i2 As Integer
)

public:
void DeletePlane(
	int i1, 
	int i2
)

member DeletePlane : 
        i1 : int * 
        i2 : int -> unit
