The Axes option allows you to add horizontal / vertical axes with x,y coordinates, anywhere on a view. To add Axes:
Select Axes 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, scaled horizontal / vertical axes will be drawn between the point entered in step 2, and the current cursor location.
Enter the second corner graphically with the mouse, or enter x,y coordinates in the prompt line, and the Axes will be added to the view.
By default, Axes will initially display Global Coordinates corresponding to the coordinates of your model. Axes can also display Local Coordinates (lower left corner = 0 , 0 ), with the Format Tool dialog.
After an Axes object has been added, it can be moved, re-sized, formatted etc. See the Edit Tools Overview topic for details.
