points, between which the role lines will attach. The default points are in the
corners of the outermost parts of the symbol.
Add point adds extra connection points. After
selecting this command, click on the desired place in the drawing area. Note
that the order of connection points is important: see Join
points.
Add Point at Center adds one connection point to
the middle of the merged rectangle for all the elements in the Symbol

points for the selected symbol elements, one at each selection handle.
