Honeybe E+ context shading component splitting surfaces

Hi!

When i input the surface attached in the example into the context shading component it splits the surface into two. This creates problems for me further down the pipeline.

Why does it do it? (starting surface is checked to be planar)

If i merge the surfaces after the context shading component has done its work, will they continue to behave as they should in e+ and hb generator?

Thanks!

Update; two merged HB surface does not work like a single surface in HB components. I could have guessed that.. :)

Hi Ludvig. EPContext component meshes all the surfaces regardless of being planar since I wanted to avoid any possible issues with EnergyPlus but now I can see how it can cause some real issues. For example I'm not sure if EnergyPlus can handle shading non-convex shading surfaces. Let me give it a try and see if I can create a cleaner version without re-writing the whole component.

Here you go:

Haven't tested it for enough cases so make sure to double check the outputs. Let me know if you found any cases that component fails to generate expected results.

Cheers!

Hi Ludvig! Thank you for the kind comments. The real thanks goes to Anton for developing all the components for HB-Generation. I just fixed my old code that I should have written better in the first place anyways. Cheers.
