Why We Need a Geometry Calculator
Occasionally, a drawing will not have enough information to program a part in the usual
way.
An example is the illustration below. The part is uniquely defined by the given
information. However, the coordinates of points C and D, where the arc is tangent to
the sides, are unknown. These coordinates are needed to define lines
002 and 004, as
well as the FROM and TO points of the arc.
