Hi Misung,

First of all a couple of information about LB components: if you see the inputs, you'll see some underscores on the right side, left side or both side of the words.
Left underscore: you need this to run the component
Right underscore: it is optional
On the both sides means: you need this but there is a default value inside, so if you don't connect a data, the component uses the default value as input.

To run LB sunlight hours analysis you need _geometry, _disFromBase, _sunVectors, _runIt.

Coming back to your issue, Have you set a Brep in Grasshopper? When a component or a parameter becomes orange there is a warning for you.

I suggest you also take a look at example files on Hydrashare:

Hello Antonello,

Thanks very much indeed for your kind comments.

I have set a brep in Grasshopper and linked every needed info(Geometry,gridsize,disfrombase,toggle). However, the problem is when I set a point component to testPts, it doesn't show up in Rhino model and when I changed Toggle False to True after linking every needed components even sunvectors, Programme stopped working and stuck.

Misung,

Could you attach your *.gh file? So I can check it.

Antonello,

Thanks! I think It's because I set up mesh not surfaces. Is it correct?

I'm not sure about it.

Misung,

 

I don't think so,  Grasshopper  doesn't let you select a brep if it is a mesh.

It seems like you have deleted breps without internalizing them.

If you connect a brep/or breps your file works fine.

Antonello,

I really appreciate your examples! Then I maybe set up too many breps which was over 40 buildings. I have figured out that if I make small numbers of buildings, It works fine. :D  Thank you very much

I suggest to check the size of your grid. It is not about the number of breps.

Thanks very much! That was the main problem I think
