As I mentioned, the pattern can be useful for alignment and spacing (though not always) and is worth making as an insurance policy. ... I agree that a pattern is a really good idea, even when laying out from scratch. In addition, we like to check the current layout by doing the stretching-a-string-from-agraffe-to-hitch thing (as if we were laying out the scale) after the bridge pins are out but before the cap or bridge comes off. Sometimes it points out little compromises the maker has made in order to make the string layout tidier or more uniform. For instance, sometimes the hitch pin line has to dodge around a plate strut. The maker will not slavishly follow a perfect line from agraffe to hitch, but will smooth things out (the side bearing has to be attended to manually on each note that isn't in a perfect line). Or the hitch pin line isn't perfect, or the agraffe spacing isn't perfect. In this case it's easy to see what has been fudged to make the bridge layout prettier, and one can copy it if desired. In a good piano it's usually done pretty neatly, and a pre-layout makes it easy to spot.
