Roof Area Calculation

[Anonymous]

Hi All,

I am trying to get ArchiCAD to provide me with total surface area of the roof of a residential project. What I don't understand is why it produces 3 different values all under separate "Surface" columns. Which one should I go with?




Thanks,

Matts

Top surface, Bottom surface, edge surface. [almost certain]

You probably have some perpendicular roof edges that make the underside smaller in area.

If you made all roofs with vertical sides, top and bottom areas would be equal

Brilliant. Makes perfect sense Thanks a whole bunch Dwight!

Have a great weekend,
