Measurement - Concepts

AGi32 provides two dynamic measurement tools for your use: Measure Area and Measure Distance.

Measure Area

The Measure Area command provides the ability to measure the area enclosed by any polygon dynamically. The area and perimeter length calculation actually takes place while you are constructing the polygon and is constantly displayed in the coordinate window below AGi32's graphics area.

The Measure Distance polyline is displayed using the "Measure distance/Area Color" specified in Tools - System Settings.

The area of the polygon is calculated by continuously tracking the mouse movement once the second vertex of the polygon is entered. You may continue to enter vertices by clicking the left mouse button, until the perimeter of the polygon encompasses the area of interest. At this point, note the area of the polygon in the coordinates window. Click the right mouse button to terminate the command.

The final calculated area is displayed temporarily on the screen until the next command is initiated.

Measure Distance

The Measure Distance command is used to determine the distance between two points (along a line), or the angle of orientation formed by the current line and an imaginary line drawn from due East (0 degrees world coordinates).

Once the first point has been specified, the distance measurement is dynamic. The length of the line and orientation angle are constantly displayed in the coordinate window below AGi32's graphics area.

The Measure Distance polyline is displayed using the "Measure distance/Area Color" specified in Tools - System Settings.

Click the right mouse button to terminate the command. The final calculated distance is displayed temporarily on the screen until the next command is initiated.

The distance of a line between two points at different Z elevations can also be measured by using the PageUp and PageDown  keys to adjust the Z coordinate of each point as the Measure Distance command is applied.
