Dellus: Thank you for adding the A0 metric template so quickly.
LibreCAD was opened - and on clicking the 'mech mm 1 1 a0.dxf', the open page of programming for the 'little' template was, and still is, quite daunting for this old brain!
Scale to be used is 1:1 and the maximum number of lines on the A0 sheet should be 40.
The plan is to overlay the Soundboard profile to the strings at 22.5 degrees, (Paraguayan harp), and allowing for bow outwards (strings under tension) use the string dimensions and tensions to mark locations for each bridge-pin, the collection of marks on each string guides the shape of the Neck in a harmonic curve.
Thanks again, a report later.
