Measuring the Area of a Polygon
You can measure the area of a polygon drawn on the screen. To do this:
1 Display the [TOOL MENU: MEAS/DRAW] screen.
2 Tap [AREA].
3 On the screen, specify points as the vertexes of a
polygon. (The figure shows an example of drawing a
four-sided figure by specifying four points, A, B, C, and
D.)
4 Tap [COMPLETE] or click the right mouse button.
If the Capture function is assigned to the right mouse button,
tap [COMPLETE], instead of clicking the right mouse button.
As you specify points, sides are drawn sequentially. When
the ending point (D in the figure) and the starting point (A in
the figure) are connected, a polygon is produced, and the
area of the polygon is displayed.
Note: Do not draw a figure where sides cross each other.
For such a figure, the area cannot be measured
correctly, and "NG" is displayed.
To continue measurement, repeat steps 3 and 4.
5 To terminate measurement, tap [CLOSE] to redisplay the
[TOOL MENU: MEAS/DRAW] screen.
