Accurate surface area on IFC


Hi people,


We are working in BIM model where a great level of accuracy is required so I am wondering what tips do you to exctract an exact surface amount out of a complex profile.


we have some vertical panels that i drawn using a kolom with a complex profile below


the calculator needs to know how many m2 of surface of the red line. 


What am doing now is a property with the entiry surface divided by 2 but that is not accurate enough considering we have 200 panels and a small difference in each one will mean a huge difference in the total.


Thanks in advance
