Trying to figure out how to get a reference to a plane embedded in a 3d sketch.  I don't see any Get methods in the iSketch interface.  When I record a macro it uses:

Part.Extension.SelectByID2("Plane2", "SKETCHSURFACES", 2.97357990743765, 0.523243105825149, 2.27042269653217, False, 0, Nothing, 0)

However if I don't know the name of the plane I really can't use that.  Any suggestions?
