Setting user measurement units (scale)
The program allows measuring
the area and perimeter of on-screen
objects both in dots and in user-specified units of measurement
(such as meters, feet…). In order to set user measurement units,
choose the "Measuring
Scale" menu item.
Draw a segment or broken line and click the
right mouse button. Then a dialog window will appear:
Here you should enter the length of the line
that you have drawn in your units of measurement. After this,
all area and perimeter measurements will be shown in your units of measurement.
