Highest point of a building

Has anyone got any suggestions to find the highest point in a building using Dynamo?
Measured from project zero.

Obviously if the highest point was a wall it’d be pretty easy but if it’s something else, its location point isn’t it’s highest Z value.

The only things I can think of are pretty contrived… Any simple suggestions welcomed. :smiley:

Even better, please tell me there’s a node for this :laughing:

ooo… I think if I draw a bounding box around all geometry and get the Z value of that it should work.

Thanks forum :joy:
