4 Points Angle
Measurement target
The line passing @
and
2 is drawn.
The angle at the
intersection
of the two lines is
displayed.
The line passing
3
and 4 is drawn.
This function draws two lines on the image and measures the angle at the intersection of them.
1. When is selected, pointer “ ” is displayed. The pointer can be moved
using the cursor buttons or the mouse.
2. Press the SHIFT button on the two points you want to specify to draw the refer-
ence line (line @-² in the figure on the left).
3. Similarly draw another line (line
3-4
in the figure). The angle at the intersection
of the two lines is displayed.
4. To measure another angle, press the SHIFT button at each of the points to be
specified newly
5. To return to the measurement menu, press the SET/OK button.
}If you are using the mouse, left-click it instead of pressing SHIFT and right-click
it instead of SET/OK.
}Either the interior or exterior angle of the intersection can be measured. For
details, see “3 Points Angle” above.
Perpendiculars
Measurement target
The line passing @ and 2
(reference line) is drawn.
The line orthogonal to
the reference line is
drawn from
3
and its
length is displayed.
This function draws a line based on two points specified by the user, then draws a line perpendicular to the reference line
based on a point specified by the user, and measures the length of the perpendicular line.
1. When is selected, pointer “ ” is displayed. The pointer can be moved
using the cursor buttons or the mouse.
2. Press the SHIFT button on the desired two points to draw the reference line (line
@-² in the figure on the left).
3. Press the SET/OK button at the desired point to draw a line perpendicular to the
reference line from it.
To draw multiple perpendicular lines to the reference line, press the SHIFT
button each time. At the last point, press the SET/OK button to draw the
perpendicular line.
4. If you want to draw another reference line and perpendicular lines to it, repeat
steps 2 and 3 above.
5. To return to the measurement menu, press the SET/OK button.
}If you are using the mouse, left-click it instead of pressing SHIFT and right-click
it instead of SET/OK.
