HB Blind Component Bugs

It seems like there's a couple issues with the implementation of the blinds component.

1. The component works fine unless the blind material transmittance > 0. If this happens, a severe error is returned:

When I manually went into the IDF and set the Slat Diffuse Solar Transmittance and Slate Diffuse Visible Transmittance, the simulation worked fine without a severe error:

I don't know how difficult it is to fix the HB component, but it would be nice.

2. The horizontal shade works but the vertical shade fails to generate a surface. I'm not sure of the reason. With horizontal blinds:

With vertical blinds:

If anyone has any insights as to what the problem is, please let me know.

Hi Burin, Thanks for finding the bugs and I am sorry for responding so late.

1. This was an easy fix and you can get a working version of the zone shades component (one that writes the diffuse transmittance) by syncing with the github.

2. I am not able to replicate the problem on my machine. I get vertical blinds on my zones when I set the horOrVertical to False:

Can you upload you GH file and I can see what is wrong with your specific case?

Burin,

Thanks for posting the file. I was able to fix the bug. It seems that it resulted from some code that Mostapha put in the North angle function, which I will admit I do not fully understand but it seemed unnecessary so I took it out.
