The above image is a simple example of our project facade.

What we want, is a bit complicated, I hope I deliver it well…

(Letters represent each row, Numbers represent each column)

We want, each piece from columns 1 and 8, to not rotate at all.

**Columns 2 and 7:**

For row A and F rotate from 0 to 10 degrees

For row B and E rotate from 0 to 20 degrees

For row C and D rotate from 0 to 30 degrees

**Columns 3 and 6**

For row A and F rotate from 0 to 20 degrees

For row B and E rotate from 0 to 30 degrees

For row C and D rotate from 0 to 40 degrees

**Columns 4 and 5**

For row A and F rotate from 0 to 30 degrees

For row B and E rotate from 0 to 40 degrees

For row C and D rotate from 0 to 50 degrees

The image below is an example of our facade (the rotation has been done by hand in rhino and NOT in gh)

Here is the sample rhino model and the grasshopper we have done for only one column but we can’t do it for the whole facade.

I hope you get the idea of the project. Feel free to ask more if you didnt get the point.

Thank you in advance.
