Points in Rectangles, Circles, and Arcs
•
Draw objects such as rectangles, circles, and arcs also contain points, but they are
treated differently.
Rectangles–Contain shape points at the four corners, but the lines between the
shape points contain no editable end points. When you click one of these shape
points, a text box displays the width, height, and area of the rectangle on the map.
Circles–Contain no shape points, but have a central point that does not display until
you snap it (see Note below) to another object. Clicking the circle displays a central
crosshair within the circle and a text box containing information on the area and
radius of the circle on the map.
Arcs–Contain three shape points. When you click any of the points, a text box
displays the angle or bearing of the selected point, the radius of the arc, and the
total length of the arc line on the map.
Only the first and second points you placed on the map when creating the arc are
treated as start and end points (i.e., show red or green when clicked). The central
magenta shape point, or third point you placed, determines the shape of the arc.
Note For information on snapping a draw object to another draw object, see
Snapping Draw Objects.
Points in Point Draw Objects
•
Point objects, such as waypoints, symbols, and text, do not have shape or end
points. Text label objects contain a point at the bottom center of the text label box
and are only visible during a snap.
