In a curved curtain wall how can I have rotating panels that are all parallel?

[infoWBN4V]

Good afternoon.

I am working on a curved curtain wall that has rotating panels. The method I used to build it is displayed in this tutorial: creating a profile and then a sweep that has a built-in rotation parameter.

The end result is a set of panels that are not parallel because the rotation angle of all of them is dependent to the curvature of the curtain wall. I have been manually rotating each panel instance to make them "look" parallel, but it's very tedious and other result is not exact.

My question is whether is there a way to rotate all the panels automatically, or a formula that calculates the angle of each panel towards a specific world or absolute orientation.

Thank you so much.

You can create a panel with a parametrically controlled angled by Instance.   Is that what you are trying to accomplish?  Or are you wanting the Instance angle to be automatically calculated and applied based on some formula?  Dynamo might get you there.  

Out of curiosity, what's the "math" that governs the angle?

Thanks for your answer.
By now there's an angle instance parameter for each panel but, since the
curved curtain wall changes direction, so do the panels (unless I change
each panel angle manually, which I don't want)
I am looking for a solution that would emulate an hipothetic copy command
along the lenght of the curtain wall, ending up with all the panels aligned
and parallel.
Thanks again.

Interesting challenge. I think I could get there.  I would use this approach:

On which axis does the panel rotate on?  Like a casement window, or like an awning/hopper window?  Can you show sketch how you want it to be?

I'll check on it. thanks

[barthbradley]

Essentially, you want to do something along these lines; right?

hanks for your reply.

Here's a plan view of the situation.

Thanks

Precisely. Along a curved curtain wall path

[barthbradley]

Well, there's definitely math to get there, so automation thru Dynamo should be possible.     

[ToanDN]

You can get it fairly easily with a mass > divided surface > a repeater of 2-point adaptive component with adaptive points set to Global XYZ.   There is no math involved except the one angle parameter to get the orientation right.

Example mass attached.  You can create different panel types with different rotation angles via a parameter in the panel family.

Thank you so much.
Does this approach involve using curtain walls?
Thanks again

Not curtain wall. This is using a curved mass form, dividing the surface to get the division similar to a curtain wall division, hosting an adaptive family on the divided surface and populating it using repeater tool.

Thanks. Well, the solution is beautiful.
Reaching this point, I don't think there's a way to achieve so using curtain walls.

Do you know if there is any video tutorial of your approach?

Thanks

You can search YouTube using keywords: conceptual mass, divided surface, adaptive family. I can post a short Screencast when get to the office tomorrow.

Awesome, thanks.
Looking forward to it.
