Hi,
So far the conversation would appear to revolve around using either square or rectangular section timbers. When round, polygonal, moulded, profiled or tapered timbers are employed then the ability to establish offset lines from references faces will become more problematic and so this might well demonstrate the ultimate value of using centre lines as a method to establish reference planes.
