Synopsis

obj = CIRCLE/x,y,[z,]r[,START,start angle,END,end angle]

Description

Creates circle by defining the X, Y, and Z coordinates in work coordinates and the radius. The Z coordinate is optional. The plane of the arc is made parallel to the plane of the current WCS.

Parameters

Parameter

Description

x,y,[z]

The coordinate values of the circle center point. If the optional Z coordinate is omitted, the center point assumes the Z value of the currently set depth.

r

A positive value which establishes the circle radius.

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.
