| 摘 要： | 以平行、相似、同向的曲线为投射线,运用相似变换,可不画投射曲线的投影,能图解传统方法不能解决的任意曲母线曲面的截交线和相贯线。由于不画辅助曲线,从而提高了图解效率和精度。

| Abstract: | Taking parallel, similar and uniformly directed curves as projecting lines, one is able, by means of similarity transformation,to represent graphically,the intercepting and interpenetrating lines of surfaces with arbitrary curved generating lines without constructing the projection of the projecting curves. These intercepting and interpenetrating lines are beyond graphical representation by peans of conventional approach. The efficiency and accuracy of the proposed approach are much better as no auxiliary curves need to be constructed. |
