I am trying to use a macro to mate two planes, but at the point the macro will run the component currently referred to as "Base Assmbly-1@POWERPACK" will be an unknown assembly that will have a "BAFRONTPLANE" and a "BATOPPLANE" in it. Any ideas?

Option Explicit

Sub main()

Set swApp = _

Set Part = swApp.ActiveDoc
boolstatus = Part.Extension.SelectByID2("Front", "PLANE", 0, 0, 0, True, 1, Nothing, 0)
boolstatus = Part.Extension.SelectByID2("BAFRONTPLANE@Base Assembly-1@POWER PACK", "PLANE", 0, 0, 0, True, 1, Nothing, 0)
