Hyperbolic Paraboloids roof

[victor93rs383115]

Hi everyone! Thanks for having accepted me into this group.

Currently I’m designing a roof that uses the style of the architect Felix Candela (composed of curved surfaces known as hyperbolic paraboloids).

In the 1st image, you can see that the roof is formed by four segments (each segment is an individual family that I have rotated and copied, however, I need to create the four segments forming part of a single family).

The 2nd image shows how each segment is obtained by doing substractions to a hyperbolic paraboloid (highlighted in blue), using Void Form Elements (highlighted in orange). The 3rd image shows the result of this operation.

The 4th image shows how I rotated and copied that segment in order to obtain the second segment of the roof.

The problem is that I haven’t been able to repeat the process in order to obtain a whole roof composed of four segments *that form part of a single family*. When I try to rotate and copy the first two segments, in order to obtain the other two that are missing, the Void Form elements become unlinked to their respective paraboloids, and thus the substraction operations aren’t performed in the new segments (5th image).

How could I make the Void Form Elements stay linked to their respective paraboloids? Do you know another method, easier and simpler than the one I’m currently using, for obtaining the roof of the first image? Perhaps Dynamo could offer an easier way to achieve this?

Thanks for your time!

I'd say Dynamo would be a good place to look.
I'm thinking there's has to be an easier way to make what you're making.
could you use one adaptive to host another.
If you have one adaptive that is just the points, can't you attach a flat extruded to it and avoid the void?
Just a thought.
Looks like a fun challenge

It looks like you are working entirely in the Conceptual Massing family environment. If you have created one of these, could you not import it to a Revit project and THEN rotate it?

Update: I just read the part that you want all this to be part of one family. Would you clarify why this is important to you?

Update 2: I created the attached by using solids, not voids! That is, I changed the voids to solids, rotate-copied the hypars and the other solids around, then used the Cut command to do the work of the voids. I created a subcategory of Generic called "Pseudo-Voids" so I could control their visibility, or just select the pseudo-voids and make them not visible. Either way, when you load this into a project, only the hypars will show up.
