Point The Point function selects the point on the polygon you want to edit. You can
use the knob to scroll through the points on the polygon, or you can use the
keypad to jump to a point on the polygon. The point selector traverses points
that are previously dened.
The scope draws a dotted line from the rst point to the last point. This
dotted line turns to a solid line when you exit the menu. Also, you cannot
cross lines as this turns one polygon into multiple polygons.For example,
in Figure 6-1, A requires two polygons, while B is not a legal construction
because B requires lines to cross.
