Solar Panels in Facade

Hi,

I am trying to make the attraction point on the end of this panels on the facade of building but still I couldn't figure it out. i wants to ask if any one know how can i make this panel as the move vertically in the facade. I kind of wants they Rotate by certain angle.

Hello Harir,

Please take a look at this first: http://www.grasshopper3d.com/forum/topics/how-to-get-help-when-you-...

You are still not providing enough information, I am afraid... Depending on what you already have (an axis of rotation for each panel? the plane of each panel?), you should choose between the many [rotate] components that Grasshopper has. But first you must specify how you want them to rotate. Do you want them all to rotate with the same angle? Do you want them to rotate so that they are all "looking at" one point? Do you want something else?

Please upload the file with what you already have and a more detailed explanation of what you are after.

Cheers, Nikos

this is what I try to move them in z direction in Y face but still this move all the panels together. I don't know how Can I make the attraction point for this panels and they all move in Y,z direction by moving the point.

Are these panels that follow the sun's beams? In this case they should rotate all together (the sun's beams are all parallel). See the attached file and let's take it from there.

Hello Harir,

Please answer these questions so I can better understand what you are after:

1. On the file "FACADE panels-02.3dm" you have some panels that are fixed on a facade on the YZ plane. Are these the final panels that you want to rotate, or is this file just an example? Do you also have panels in other facades (in other planes)? Is the positioning of the panels random? Is it completely random, or are there some rules? Are the dimensions of the panels fixed or can they change, and how?

2. If I understand correctly, you want to have 2 different rotations, right?

2a. The first rotation is around the edge of the panel that lies on the facade and you want it to be between 0 and 90 degrees, right? How is the angle for each panel defined? Based on the sun's beams direction and, if yes, how exactly?

2b. The second rotation is around the X axis, on the right point of each panel (which is fixed on the facade) and you want the angle of rotation to be specified based on an attractor point, right? Is there a minimum and maximum angle or do the panels always align with the attractor point?

For a better understanding of these questions, see the attached definition (open it together with your 3dm file). Here the first rotation is the same for all panels and is controlled by a slider (until you explain how you want to define the angles). The second rotation doesn't have any constrains, so the panels always "look" at the attractor. But, as you can expect, strange thing happen this way: Panels hit into each other, rotate until their solar side is looking downwards, etc.

Still, I believe, if you answer the above questions we will get somewhere.

Cheers,

Nikos

Yes, thank you so much. This is what I wants to make.

This is perfect , just one more question if I need one more attraction point .Is that work by adding one more point ?

Thank you sooooo Much Nikos

No, I am afraid it's not that simple... Right now each panel turns towards one point. If you have 2 points how do you want the panels to behave? Chose one of the 2 points? Based on what? Distance? smaller angle?
