The Ruler tool can be accessed in the toolbar at the bottom right of the Game Board, regardless of mode. It is a simple tool that gives you the option to measure distances.
From the place where you clicked a line is drawn with a number showing the distance to your mouse cursor, until you release the mouse.
space on the way will set waypoints so that you can measure distances around objects, easily.
It shows the first decimal to support using the metric system with games that were devised with the imperial system in mind (e.g. the standard 5-ft grid in D&D translates to 1.5 m).
If you turn on the
Share with others option that opens up above the
Rulerbutton in the toolbar, this will be publicly visible for all players in the session.
If you turn off this option, only you will see the ruler.
This setting will also be used by the ruler built into the select tool.
