conceptual modeling - dividing surface

I am in conceptual modeling
I would like to create a facade with standard panels, so that we can easily mount it in operation


see the annex
above I have a flat surface with abcd points on the same horizontal level
I've "divided the surface" and I've created a guilloche with all the same figures among them, so the facade panels would be easily mounted

now in the figure below.. I have the same surface, but I lifted a top up, and the grid changed, allowing the outer edges
therefore all different "panelli" have been created, which is impossible to have in a project.. .

is there a way to have cmq a grid with all the same panels?
Thank you very much

 

[kubbah]

to make more clarity
I'll show you what I'm getting thanks to the commando "divid surface"
and what fostered in his project (the effect I would like to achieve, together with equal elements that comongon the roof or facade)

 

[kubbah]

my question therefore perhaps should concern the theory of surfaces:
is it possible to divide a complex nurbs surface into a set of equal elements? or similar for acceptable approximation orders?

the example of the fucsas fairhttp://sullarte.it/photogallery/2007...isecondo_0.phpare all different panels here?

 

[gfrank]

if I use the conceptual modeling, by the online guide of revit, if not mistaken, it is evident that the division with equal "elements" is feasible only on flat surfaces, but not on the complex ones.

hi, to solve your problem you could build your "pannelli" through lines and not from the subdivision of a surface.
In this way you decide the measurements of your "pannelli".

 

[kubbah]

Yeah, but then to model them? a curve or any other form?

I don't think I understand.
is your problem not to get a grid with all the same panels?

 

[Fulvio Romano]

I would do it by projecting a grid of lines on your surface. only then you have to fix it by hand to make the surfaces look the same. then inflating the grid where the surface is more inclined than the projection plane, and vice versa.

revit does not contain a divid command that then "fits" by hand.

No, no, I mean, do the lines and then the "projects" on the surface. The projection is quite common, but I don't know revit...

 

[kubbah]

I'm sorry, but if you don't know revit, how come you answer questions about revit?
If I had to draw a grid and then project it on a surface, I would do it with another program and not with revit,
in the revit it is not to make a nice drawing, but to get really panels, or components of real size, parameterizable, it is not a single cadist representation

Let's talk about cad, that is, "drawing assisted by the computer". assisted, not made by the computer. revit is a tool. to do what you say there are automatic tools (I don't know if revit is one of these because I don't know it), but there are also manual procedures.
so much to understand, the dock of the ships from cruise is made to "pannelli", that they must be of date form, and then developed. until a few years ago it was done with the pencil and the team. techniques exist and can be applied in any cad, although this does not have specific and automatic means.
I was proposing a method I use often. But obviously it's not what you're looking for.

 

[kubbah]

so you would propose to project it on a surface, and then adjust any value of the side of the element (pannello)?
revit I think you do not project lines on a surface yet (as gfrank says)

 

[Erikilrosso]

if I have understood you would like all the perimeter elements of the panels that make up the surface to be parallax between them? (rectangles, squares,...) and were not "striped" or "enlarged" according to the perimeter of the concave or convex surface?

 

[kubbah]

I would like to get a number of equal elements between them,
Tots equal
and not all different,
can be triangles or other forms
I don't want everyone to be different here
quidni I'm looking for a method to parameterize and manage to control angle distortions between different panels

 

[gfrank]

... I believe that with the subdivision of a "oval type" mass in equal elemetes, it is not possible.
in my opinion, taking example from the figure of the first post, you should force the supporting structure: parallel curve beams (to the short axis) with constant interassesment, with reduction of the diameter towards the "polies" of the mass, then models you a generic family of curved panel according to the arc (parameter), and with inclination parameter (parallele to the long axis)
this family of panels, inserted at the top of each "arch" created by two consecutive beams, covers it with an angle matrix (predeterminating the center of the arc)
repeat the procedure on each sector consisting of two successive beams, adapting the panel (curve and inclination)
at the base of the dome, the panels will be cut through solid subtraction

 

[ocraM999]

I mean, like that?
in this case the panels are identical only for horizontal bands, and is the best condition.
consider that it is not possible to obtain complex surfaces with few equal panels for e.g.: the Milan fair is formed not by tens, not by hundreds but by thousands (sic!) of different panels, there are on the net some articles in this regard.
observes a sphere or a football, the best you can get is a composition of pentagons and hexagons, that is only two panels (which you can split into triangles if you prefer, but does not change...).
