摘　　要：图形的角度线有多种多样,但都可以归结为过已知点与水平方向成一定夹角、过已知点与上一段直线成一定夹角、与已知圆弧相切且与水平方向成一定夹角等情况。这些角度线利用AutoCAD可以有很多种绘制方法。不论有多少种绘制方法,总能找出一种最简单最快捷的绘制方法,利用最简单的方法绘制角度线,将大大提高绘图效率,降低绘图难度。Although the graphic angles are varied,they can also be reduced for the known point and horizontal direction with a certain angle. Such as a known point and a straight line form a certain angle,and tangent to a known arc with horizontal direction forma certain angle,and so on. Above all of these angle lines could have many kinds of drawing method using AutoCAD.No matter how many kinds of drawing methods there have,we always can find out a most simple and fast rendering method to finish our drawing.When we were doing line drawing with the simplest method,we would greatly improve the efficiency of drawing and reduce the difficulties of drawing.
