PURPOSE:To reduce the quantity of handling data by transforming many basis patterns into hierarchies. CONSTITUTION:Basic patterns A, B and C are defined as a set for production of 12 drawing pattern data including groups (A1, B1, C1)-(A4, B4, C4). In this case, these pattern groups are regarded as D1-D4 and furthermore, these pattern groups D1/D2 and D3/D4 are regarded as E1 and E2. Then both pattern groups E1 and E2 are regarded as F. These basis patterns are transformed into three hierarchies D, E and F. A 1st memory stores programs in number corresponding to the number of those hierarches and the data on the sizes of fine a patterns forming each basic pattern. While a 2nd memory stores the drawing position with respect to the position of the lowest hierarchy area of each basis pattern. |
