【Abstract】 This method is different from parametric template method. The main difference is that the drawing is treated as a whole and uses the common properties or various kinds of drawings, which are characterized by the idea that mechanical drawings are tangent to a con- trol polygon. The difference between any two drawings is merely that they have different con- trol polygon, i.c. with different values or vertices and radii. Therefore, a general program for plotting such drawings can be written.更多还原
