Creating a Great Circle

Use the Great Circle tool to place a great circle object over the drawing. Unlike a 2D dimension that shows the linear distance between X and Y coordinates in 2D, a great circle is an arc that shows the shortest distance between two points on the sphere-shaped Earth. Use the Great Circle tool (instead of a 2D dimension tool) to measure distances in a georeferenced drawing.

To create a great circle:

1.      Click the tool and mode, and then click Preferences.

The Great Circle Properties dialog box opens.

Clique exibir/ocultar parâmetros.

2.      Click the drawing at the beginning point of the great circle, and click again at the ending point to create the object.
