Great tip
just a quick question
I didn't find the location component, It's useful :)
Maybe it appear in future version, right?

Hi Mohammad,

You're right. I attached decompose Location userObject. Drag and drop it into grasshopper canvas.

Hi, Mostapha!

I am trying to make shadows for my projects in the university but I have the new version of ladybug and some components not the same...so it is difficult to understand what to connect because components differ now. Could you please help me to find the problem in my definition?

You need to connect the location output from the importEPW component to the location input of the sunPath.

Thank you, Abraham! It works now...but too slow...and one more question. If I set up the grid size even to 0.5 it really can not work, it is loading the system too much...so I can work only with a grid size of 4 but shadows becoming with a lot of pixels. Is it possible to adjust this situation?

Nothing much to do about this Yana, but ...
Pick the geometry you really need to get the shadows on. Maybe not always you need all of it.
Reduce as much as you can the ground surface. Sometimes you don't need to go so far.
Use for the ground a single surface instead of a box.

Hi Yana, I would also set Parallel to False. It takes so much extra memory. Technically there should be no limitation for grid size. It can take long but it should produce the results.

Hi,

I saw the youtube video you posted of this definition, just wondering where you plugged in the panel showing the area of the shadow cast??

Not sure what you are asking, but just in case, you mean the "geometry" input in the LB_sunlightHours?

Sorry I didn't realise the youtube video isn't linked...

In the definition in the video there is a panel in the bottom right which seems to be showing the area in m2 of the shadows on the ground surface. It has a receiver and I can't see which output it's gathering its data from. Any chance you might be able to help?
