Shading mask - Ladybug , geometry issue

[Manis]

I’m modelling a shadow mask for a proposed building.

The North- east and North -West facing windows have shading. I wanted to see if either vertical or horizontal shading would be fit for the windows. However I am not getting the correct result output from the shading mask.

The building was imported from sketchup and some parts were removed for the ease of usage. The window is like a double window where one on the bottom is openable whereas the upper part of the window is not and the vertical/ horizontal fins are placed at the upper level.

To show the generated shading, I have placed the points at the sill level 0.01 m above it of the bottom most window level.

The results:

Isnt the result supposed to appear like the image below?

I have attached the grasshopper - ladybug file for reference. However I m not able to upload the geometry separately if required.

Without the geometry it is hard to say. In any case, the “image below” corresponds to a south oriented window and you case looks like the north is rotated.
-A.

Thanks @AbrahamYezioro, Yes the case above is north oriented.

Here are some images of the 3D model. Here is the drive link for the geometry for reference (Model)
