Railway curves are generally too large a radius to draw with a compass, so what used to be done was to have a set of "Set squares" with radii from 25mm to 1000mm in increments of 25mm. Amongst other things, the point of the compass would be off the page, if not off the table.

Famous quotes containing the word planning:
“Sensuality takes planning and work.”
—Mason Cooley (b. 1927)
“...A shadow now occasionally crossed my simple, sanguine, and life enjoying mind, a notion that I was never really going to accomplish those powerful literary works which would blow a noble trumpet to social generosity and noblesse oblige before the world. What? should I find myself always planning and never achieving ... a richly complicated and yet firmly unified novel?”
—Sarah N. Cleghorn (1876–1959)
“In preparing for battle I have always found that plans are useless, but planning is indispensable.”
—Dwight D. Eisenhower (1890–1969)
