<p>The appts. comprises display with a control arrangement indicating as head items, addresses comprising the designation of a straight line or an arc for a planar graphic pattern. Other designations includes a vector angle of the straight line or a radius of the arc, the vector components of the straight line or coordinates of the center of the arc and modifiers. A data setting arrangement operates by successively using addresses displayed and is indicative of the straight line and the arc derived from the planar graphic pattern. A memory stores the addresses, the set data and formulae. A computer calculates the set data according to the formulae to determine the addresses of unknown data which have not been designated numerical values by the data setter.</p> |
