know the cumulative surface of many 3d faces

[Dario1982]

hello to all, I have a problem: I have a 3d design in which dtm is present, the triangulation of the ground to understand us. . I would like to calculate the total area covered by the relief, but the individual "triangolini", as objects, are "faces 3d". There is no way to calculate the total area? As for example, you can do with 2 separate dashes, which select them both, in the properties the item "coupling area". .is there anything like it for 3d faces? Thank you!

in autocad I do not find out; autocad civil 3d makes it...

area 3d o 2d?
