No-Sky Line Analysis

Hi All,

I’m looking to produce a No-Sky Line analysis (the boundary where internal sky view ends) in line with BRE BR209: Site Layout Planning for Daylight and Sunlight - 3rd Edition and (BS) EN 17037. I’ve modified a recipe in honeybee and used a simple geometry to test. I’ve managed to produce results however, the results don’t look as expected and don’t match the results produced by IES-VE with the same geometry. Can anyone see where I might have gone wrong with this analysis.
