摘要
介绍了AutoCAD中绘制椭圆弧的两种方法;并结合图形详细说明了用这两种方法绘制椭圆弧时要解决的两个问题:一是确定椭圆弧起点和终点角度的0°位置的问题;二是椭圆弧按哪个方向绘制的问题。
Two methods of drawing ellipse arc in AutoCAD are introduced.Combined with graphics illustrates, two problems in drawing an arc by the two methods are solved. The first problem is to determine the position of 0 degrees elliptical arc starting and ending point, the second problem is the drawing direction of the ellipse arc.
