Brilliant Ken, i would never of thought of doing that. So much easier to do.
DIdnt think ill be learning tricks like that when i woke up today.

The particular trick I described was common knowledge among layout artists back when dirt was still new, when the tools included only a drafting board, t-square, triangle, a sheet of vellum, and a pencil. Today's computers and Desktop Publishing software have replaced the brilliance and ingenuity of such simple solutions to a given task.

Steve's technique of using an ever expanding relative scale, rather than a system of absolute measurements, is definitely reminiscent of such old school ingenuity.
