7.1 Closed lines

A line is defined as closed when its end point is defined.

7.1.1

Line – end point (G1 X.. ; G1 Y.. ; G1 X.. Y..) The end point may be defined with one or two coordinates: G1 X.. G1 Y.. G1 X.. Y.. If the end point is defined with only one coordinate, a line parallel to one axis is specified. If the end point is defined with two coordinates, a sloped line is specified. The line may originate from another defined point. The line may originate from an open circle; in this case a tangent condition with the circle is forced. In this case the end point must be defined with both coordinates and must be external to the circle, otherwise the error CN3314 is issued. The line cannot originate from an open line.

7.1.2

Line – end coordinate and slope (G1 X..QF.. ; G1 Y..QF..) G1 X.. QF.. G1 Y.. QF.. The line must originate from a defined point. Starting from the known starting point, the programmed coordinate is reached with an element having QF slope. G0 X40 Y0G1 Y10 Y30 QF120 X15 X0 QF210 Y40 QF135 X-40 X-50 QF-120 Y0
