I got some strange results when the target building geometry is not included as part of the context geometry for the Sky View simulation using the View Analysis component:
There is no such problem when using the same workflow for Sky Exposure simulation.
I assume the target building itself will be automatically included as part of the context geometry due to consideration of self-obstruction …
Hope you can kindly advise!
Thank!

Thank you very much for finding this bug. I can’t believe that I made a mistake as simple as putting a “<” when I should have put a “>”. So the component was actually doing the opposite of what I said it was in the description.
In any case, I have fixed this on the github now and in the attached file.
Also, FYI that for surface-based Sky View Factor or Sky Exposure Factor calculation, pls set a very small distance between the test points and the target surface, like 0.01m or even smaller, to avoid getting zero values when the test points are located right on the surface, or getting overestimated values for test points on vertical surfaces that are positioned very close to the top edge of the surface.
