PURPOSE:To enable an operator to easily define a curve without being conscious of the arrangement order of the curve by providing the title device with a means for automatically rearranging inputted curve shape defining data and arrangement position data. CONSTITUTION:Curve shape defining information for defining a curve and the arrangement position information of a curve are inputted from a curve shape defining information/arrangement position information input means 1 and stored in internal data 2. Curve shape defining data are rearranged by a plural-curve data rearranging means 3 on the basis of arrangement position data stored in the internal data 2 so that spatially adjacent curves are adjacently arranged also in the data. A curved face calculating means 4 calculates points on a curved face from curve data rearranged by the means 3. Consequently, the operator intending to define a curve can easily define the curve without being conscious of the arrangement order of the curve. |
