The Measure option allows you to measure the distance and angle between any two points on a view. To use Measure:
Select Measure from the toolbar or the Add Tool sub-menu of the Tools menu.
Enter the first point graphically with the mouse, or enter x,y coordinates in the prompt line. NOTE: the Snap options are available in the right-click menu, if you want to snap exactly to certain coordinates.
As you move the mouse, a line will connect the first point to the current cursor location, and the length and angle of the line will be displayed on the screen.
Enter the second point graphically with the mouse, or enter x,y coordinates in the prompt line, and the Measure line will be added to the view, with the length and angle displayed.
After a Measure line has been added, it can be moved, re-sized, formatted, etc. See the Edit Tools Overview topic for details.
NOTE: for more flexible length and angle dimensioning, use the Dimension Tools options, rather than the Measure option.
