ABSTRACT
In the Support Columns A turn sign placed in the support column indicates a turn of the whole body on its support, usually one foot or the other. During such turns the foot swivels on the floor. To show turning on both feet the symbol is drawn across both support columns. Note the meaning of the following:
b
DEGREE OF TURN
c
e
The amount of turn accomplished is stated within the turn sign. Black pins are used to indicate the degree of turn, that is, the relationship of the new front to the front established just before the turn. This previous front is like the number 12 on a clock, and the black pins can be likened to the hands of the clock moving clockwise or counterclockwise through the possible degrees of rotation of 1/8,1/4,3/8, 1/2, etc. Note that these degrees are relative, the destination reached by 1/4 turn right would require 3/4 of a turn left.
