【Abstract】 According to the characteristic of the scanning engineering drawing, a method of graphic parameter driving based on the graphic understanding is discussed in this paper. And the axial dimensional chain and the dimensional deriving tactics are presented. On the base of graphic understanding, the parametric driving of recognized graph is realized also with the general geometric reasoning method.更多还原
