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:
“Few men in our history have ever obtained the Presidency by planning to obtain it.”
—James A. Garfield (1831–1881)
“In the planning and designing of new communities, housing projects, and urban renewal, the planners both public and private, need to give explicit consideration to the kind of world that is being created for the children who will be growing up in these settings. Particular attention should be given to the opportunities which the environment presents or precludes for involvement of children with persons both older and younger than themselves.”
—Urie Bronfenbrenner (b. 1917)
“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)
