Electronic Rule

      Disclosed is an electronic rule that makes it easy to draw
straight lines and curves on the display of a PC or workstation.  By
tracing the shape of the rule displayed on the screen, a user can
obtain various lines without knowing the coordinates of any points on
the lines.

      The Figure shows an example of the use of this rule.  The
displayed rule is semitransparent and has graduations.  The system
calculates the coordinates of the outline of the rule.  While the
rule is displayed, the result of this calculation allows a user to
draw lines on the out line of the rule.

      In this way, a user can draw a line CD on a line AB exactly
without knowing the coordinates of C and D in the figure.  The rule
can be applied in drawing programs.
