Hello guys,

I am using Honeybee for the radiation analysis and I came across this issue. For a round building with an atrium, the analysis is carried out incorrectly. I checked the vectors and they are facing the right direction. Interesting thing is that the problem occurs for test points located right on the edge of the inner arch.

Anyone experienced similar behavior? Any ideas how to deal with that?

Thanks a lot!  
Ondrej
