Planning
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:
“When we are planning for posterity, we ought to remember that virtue is not hereditary.”
—Thomas Paine (1737–1809)
“Most literature on the culture of adolescence focuses on peer pressure as a negative force. Warnings about the “wrong crowd” read like tornado alerts in parent manuals. . . . It is a relative term that means different things in different places. In Fort Wayne, for example, the wrong crowd meant hanging out with liberal Democrats. In Connecticut, it meant kids who weren’t planning to get a Ph.D. from Yale.”
—Mary Kay Blakely (20th century)
“Play for young children is not recreation activity,... It is not leisure-time activity nor escape activity.... Play is thinking time for young children. It is language time. Problem-solving time. It is memory time, planning time, investigating time. It is organization-of-ideas time, when the young child uses his mind and body and his social skills and all his powers in response to the stimuli he has met.”
—James L. Hymes, Jr. (20th century)
