Maximum Height in setting Link planner in a new project

Good evening to everyone, It´s my first time to planning in this tool and when I need to setting the first point I can see that the system ask me put the maximum height, the question that I have is: I need to consider only the height of tower? but if this tower in on the building should I put the tottal height? Tottal Height=height(tower)+height(building)?

Please I need to know it please.

Thanks

Total height( building +tower)

Thanks for your answer, but I need to add another opinion like Cambium to compare it too.

The maximum height should normally be the height above ground level, including any building height, however please check the ground height at the ends of the link and confirm that these match the expected ground heights. Please see the following section in the LINKPlanner User Guide for more information on the terrain data, http://linkplanner.cambiumnetworks.com/doc/path_profiles.html
