The Difference overlay of the Heatstress overlay and additional information in the hover panel.

The Difference overlay displays the difference between the original and the maquette or planned state of a specific (dynamic) grid overlay to which the Difference overlay is linked as child overlay. A hover panel provides additional information on the occuring difference in a hovered over cell in the 3D World, in the same units or terms as the parent grid overlay uses. The Difference overlay is primary created to visualise the impact of a specific action or measure on its parent overlay, and on the 3D World in general.

A few examples of where the Difference overlay can be usefull are:
