Sunshade same panel.

Hi, i´m an architect from Europe. I want to paneling a surface which i want to sun analyse.(ecotect) Must be a repeated exactly same panel ( standardize construction, which only one piece repeated along the surface). I´m trying with paneling tools (seems no to vary the panel, but i´m not sure) and i want to try grasshopper and paracloud. I want to know your opinion, what is the best way to achieve this?

thanks in advance.

You can do this with Grasshopper very easily. How does the Ecotect data affect the panels if it's always the same panel? How complex is the surface? What's the shape of the panels?

How does the Ecotect data affect the panels if it's always the same panel?
Of course i plan first achieve the exact modulle repetion to export to ecotect.Then i would do 3 or 4 panel solutions and export too. I know it´s faster parametrize the panel in GH, but first, i want to learn how to get an exact panel repetions along a surface. (more Later... :)

How complex is the surface?
Actually it´s a wavy green transitable roof. .-Any tips around this?

What's the shape of the panels?
Regular module, rectangular or triangulated. .-Influence of the panels?

This is what i get with paneling tools (attached file), but i think this module isn´t the exact dimensions along the surface.This is an example roof with the structure and the panel i want to probe.Ppanel is the perforated sheet.(still not placed)

Thanks in advance.

sorry for the size.

You can't panel a double curved surface using the same panel size without gaps or overlaps in between panels.

Can you send me a link please?

My statement didn't refer to Grasshopper. You can't do that at all no mater what software you are using because it's not possible in real life. Only certain ruled surfaced can be paneled this way, like a cylinder for example.

Maybe adjusting the surface to minimize the gaps... (and fill with resines)

I understand, only ruled surfaced; cilindrical, conical, toroidal,hyperbolic, hyperboloid, hyperbolic paraboloid, helicoid spiral... Which not?
and the doubly ruled ones?

thank you Vicente.

It depends on the shape of your panel. If it's rectangular, i think you are pretty much limited to extrusions (if you want the 4 edges to match perfectly).

so..is possible to fit (with some work and filling the gaps) a rectangular panel into a double curved surface? or you refer to the ruled ones?
what a mess :P

Yes, you can. You'll have to use a much smaller panel than the one you currently have or you'll have to use a lot of resine :P
Depending on the surface, you could for example divide the surface into a grid where the more concave parts will have bigger gaps.
If you surface has one main direction, you could slice the surface perpendicular to that direction so that you end up with thin strips the width of a panel and depending on the length of the strip, you end up with more or less panels. There are probably many ways of doing this depending on the surface you have and how the panels are going to be fixed, tolerances, etc.

Interesting, any link to start learning all of this stuff?

So fitting the panels by strips?

What about the ptGridSurfaceUV command in paneling tools?

thanks Vicente for your answers
