I’m trying to run a radiation analysis over multiple buildings simultaneously (like my earlier post about view analysis). I’m using the recolor mesh component and the results look correct. I can separate out the analysis mesh and the results on a per building basis.

But as I understand it, to get the total radiation per building, I need the radiation/m2 at each test point and multiple this by the area per face. But the issue is, how do you **quickly** get the area of each face? I thought I could use the Face boundary component but it turns out some of the faces are planar. I’m not sure how this happens as the original geometry is all orthogonal. Converting faces to surfaces and calculating areas is going to be too slow.

Any suggestions?

Thanks
