中心点，与圆弧上的点

Synopsis

obj = CIRCLE/CENTER,point1,point2[,START,start angle,END,end angle]

Description

Creates a circle by specifying a previously defined point on its arc (point is used to calculate the radius), whose center point is also previously defined. You may also define start and end angles for the circle.

Parameters

Parameter

Description

CENTER

Minor word that indicates that the center of the circle is an existing point.

point1

A previously defined point which establishes the center of the circle.

point2

A previously defined point which the arc passes through. The point may lie on a non-constructed portion of the arc.

START

The optional parameter START indicates that the starting angle for the arc is to be specified.

start angle

The starting angle of the arc as measured from the positive X axis of the work coordinate system.

END

The optional parameter END indicates that the ending angle for the arc is to be specified.

end angle

The ending angle of the arc as measured from the positive X axis of the work coordinate system.
