When this icon is selected, the additions to the path consist not of lines, but of Bézier curves. The control points of these curves will initially lie on a straight line between the end points, so the curve appears to be a line.
If you selected the icon Round Curves Automatically
, the
control points will be aligned immediately to produce continuous
curves through the points. By clicking the icon Select / Move
Points
, the control points can be moved as required.
