机件表面交线简化研究

机件表面交线绘制复杂,绘制方法为利用辅助面求公有点,再通过公有点进行描线。这种方法需要作大量的作图辅助线,极大地影响设计效率,其简化画法是一个非常值得研究的问题。圆弧直线法由等曲率圆弧和直线替代变曲率曲线,好画好描的圆弧和直线完全可以保持图形的真实感和绘图效率;模糊图示法根本不考虑交线的真实形状,而用一种意会的方法来进行更简单、明了的抽象表达。在不影响对图形的理解条件下,圆弧直线法和模糊图示法这两种简化方法简单可行,提供了简化的思路和方法。

Simplified studies on intersecting line of work surface

To draw an intersecting line of work surface is too complicated,which may apply a secondary surface to seek a common point through which a line is plotted.With the approach a lot of auxiliary lines are required to draw which will affect design efficiency tremendously,therefore a simplified drawing is necessary to study.Arc straight-line methodis proposed to replace variable radius curve with invariable curvature arc and straight line.Thus graphic with sense of reality and efficiency of drawing is maintained...
