Urgent problem with dynamic facade


I’m studying architecture and I wanted to create a dynamic facade of a football stadium with hinged windows which should be able to open up to the front as well as the back. The windows have a raindrop shape and when open they should look like shown in image 1. For the element shown in image 1 I split the surface in rhino and then created a grasshopper file for rotating the 3 parts of the window.

My problem is now that I do not know how to split the single surfaces in grasshopper all at once and then create a file for rotating the all the parts at the same time.

Thankful for any advice

This isn’t very clean, I didn’t have much time to spend on it. I hope it helps.

Unless you have a super powerful PC, I would suggest to avoid selecting all of the surfaces at one time.

Hi @monika.ladner,

Here’s a solution where you input triangles as closed polylines and grasshopper does the rest.

Thank you so much!!
But I still have problems with rotating the elements.
Although they are selected and I changed the factor of rotation they stay closed.
What could be the problem?

In the view you show it’s looks like it could be your preview setting. Deselect “Only draw preview geometry for selected objects” button in the top right.

When you bake are they open/closed?

Yeah that was it :slight_smile:
I deselected that button, now it works!
Thanks again, was a great help!
