<p>PURPOSE:To improve the workability and the plotting accuracy for the title method by deciding plural coordinate points in response to the normal size and correcting automatically a sketch into correct size based on those coordinate points for plotting. CONSTITUTION:A sketch having an external form which is nearly approximate to the form of a plotting subject is inputted in a one-stroke drawing way. Then the pattern of the sketch is recognized together with analysis of data on the sketch. The dimensional values of distance, diameter, angle, etc., are inputted in the least necessary amount to decide plural coordinate points in response to the normal size. Based on these coordinate points, the sketch is automatically corrected into the correct side for plotting. Thus the workability and the plotting accuracy are improved and the input of the external form of a pattern that has a large rate in the CAD designing time is simplified even in case an exclusive operator performs a plotting operation. Then the CAD designing time is shortened.</p> |
