The measuring tool inside of Santos Pro/Lite can be used to measure from markers, objects, and/or avatars to other markers and objects. Markers can be placed anywhere in the environment, but can also be placed on the normal, corners or the vertex of any object for a more precise measurement. Markers can also be placed on the ground for height measurements. The tool provides visual green and red lines and threshold marks to see if any measurements are above or below the threshold.
