Most of the drawings in this book have been drawn as if constructed on an A3 sheet of paper – i.e. of dimensions 420 mm by 297 mm. To make this possible the following settings have been made for a template for use when making these drawings:

Limits – set to an origin of x,y 0,0 and limit of x,y 420,300. Thus when a drawing is printed full size (scale 1:1) each coordinate unit is equivalent to 1mm.
