between internal structural frameworks and non-bearing skin elements, this approach promotes heterogeneity and differentiation of material properties. The project demonstrates the notion of a structural skin using a Voronoi pattern, the density of which corresponds to multi-scalar loading conditions. The distribution of shear-stress lines and surface pressure is embodied in the allocation and relative thickness of the vein-like elements built into the skin. Its innovative 3D printing technology provides for the ability to print parts and assemblies made of multiple materials within a single build, as well as to create composite materials that present preset combinations of mechanical properties.

ther and further into a rabbit hole that has many entries AND NO exit (metaphorically and/or literally).
SPAM ON:
If you don't like membranes ... the next best option is to use some Ball Pivot Algo (NOT delauney) > triangulate the @%$@ points > create an airy truss (with W depth) > put some shading panels (or fins or something) in all modules (or some) > job done > WOW and sensible.
SPAM OFF.
3. What the greatest Ever (Mies VDR) could comment in this occasion?
4. Dark gray stuff included is a start for very big things that would happen if ... well ... who can tell? I hear you: but you intend to use code for these big things and I have no idea about all that freaky stuff (not to mention that I'm a novice) > are you a freak and/or a freak or maybe a freak? (Moral: life sucks).
5. As I said many times we must speak for long for that one. Wonder what I had in mind when I've proposed that ... well ... many replies before, he he.
Solution: phone/skype/do something…
hings like the above (say using the Brep edges + some "interconnecting" curves) is OK but only if this is some sort of decorative/artistic/academic stuff.
2. But the problem is that is not ... thus avoid at any cost this catastrophic way of thinking (tres a la mode these days, truth to be said). Why? because this is as far from engineering as a Skoda is from a Bentley. For instance imagine the cost of bending IPE/HEB/HEA/C members in order to approximate a given curvy edge. Then imagine the bespoke nodes etc etc. Then imagine the skin (avoid rain). Then go to Louvre and spend a week studying the Pyramid.
3. Use Mesh Machine and achieve a meaningful "rigid" (kinda) triangulation (planarity by default) and THEN attempt to convince ExoW to work (good luck).
4. If ExoW can cut the mustard ... well then there's only a trivial thingy left: spend zillions and create the "liquid" nodes. Why?
5. Plan B: skip 4 and create a rigid W depth truss with good old triangles. …
ve got the problem earlier, and it is the following:
In the definition that i am submitting you wil see that from a given surface I get a family of UV points, playing with'em I sort'em until i get, in one hand, 6 vertices in each branch, in consecutive order, in the other, a family of boundary hegagon lines.
The first problem is that i can't make a surface with straight boundary, it interpolate curves (option 3 in my definiton) If I could control the degree some how....
Trying to solve it with a mesh hull it does nothing but a open brep, with no surface displayed (option 2 in my def.)
Trying the same but with boundary lines, it solves a surface (a family of them) but faceted. In this case I tryied to make a surfacebox (SBox) but I don't know which domain2 is asking me to connect.
Sorry for such a love letter, but please help me out¡¡¡¡¡
Thannnnnnnnnnnnnnnnnnnnnnnnnnnnks
P.S. the definition recycles the first part of another definition found in thin forum.…
rds of the bottom left corner of my SRTM file, and just adding the shape with the heron component in charge of it.
But i was troubled by the boundaries of the SRTM : when i set a rectangle with exaclty 1°Lon and 1°Lat (which are in my lat : {78.58245, 111.132366} [km]) the component fail, saying "index out of range", and that even if that same component is telling me that my SRTM file has a topoextent of "Rectangle (w=78.647935, h=111.224977) [km]"
i calculate the difference which are respectivly 65.485m and 92.611, and it appears to be exactly 3". I then figured out that it was the overlapping zone of the SRTM file.
so my questions are :
1 - How heron is dealing with this overlapping zone ? does it deletes them ?
2,3 - As i figured out that there is only 2 side of the 4 which are overlapped, in France it seems te be the North and Est sides i am right ? And is it the same everywhere else ?
4,5 - How can i be sure to load the entire tile ? And the same for the shape files ?
thanks…
t was a bit of nightmare - this is much more streamlined.
I must admit, matching face edge angles w/ ea face edge midpoint was a bit of a noodle baker (hence the sorting operations to get everything uniform).
Maybe I can streamline some more...

nel adopts the shape of the host surface but is there any way to restrict the panel dimensions (W*H) to a specific maximum number?
2. I see that now parameters (minimum panel height and width) do not work. And only the Minimum area can control the panels. Is there any way that I can control the panels by their minimum height and width?
I actually want to cover the maximum surface with the panels within certain dimensions of the panels.
Is that possible through Surface Panel Mode?
Thanks a lot!

Horticulture and Landscape in same time.
The most common plastic materials used as agricultural films are the low density polyethylene (LDPE, with a density less than 0.93 kg m−3), the copolymer of ethylene and vinyl-acetate (EVA)
Also here you can find the characteristics of the flexible materials for greenhouse covers (adapted from CPA, 1992 and Tesi, 2001) as much as i get.
UV-PE Film ( UV-PE~ polyethylene Long life or UV)
Thickness (mm) = 0.18
Direct PAR transmissivity (%) = 90
Diffuse PAR transmissivity (%)= 86
Long-wave IR transmissivity (%)= 65
EVA Film ( EVA~Ethylene vinyl-acetate copolymer)
Thickness (mm) = 0.18
Direct PAR transmissivity (%) = 90
Diffuse PAR transmissivity (%)= 76
Long-wave IR transmissivity (%)= 27
and here you will find the global heat transfer coefficient’ (K in W m−2 °C−1) for the above greenhouse covering materials, measured under normalized conditions (temperatures: exterior: −10°C, interior: +20°C, wind: 4 m s−1). (Source: Nisen and Deltour, 1986.)
Cover Clear sky Overcast Sky
Single PE 8.8-9.0 7.1- 7.2
Single EVA 7.8 6.6
Note : the PAR radiation (photosynthetically active or photoactive radiation and its the amounts to 45–50% of the global radiation; Berninger, 1989)
The name PAR is used to designate the radiation with wavelengths useful for plant photosynthesis. It is accepted that the PAR radiation ranges from 400 to 700 nm (McCree, 1972), although some authors consider the PAR from 350 to 850 nm.
The composition of the radiation changes with time, as a function of the Sun’s elevation and the cloudiness. When the Sun is low over the horizon, the short wavelengths are reduced (less UV and more red). The clouds reduce the amount of energy, greatly decreasing the NIR.
The PAR proportion in relation to the global radiation increases with scattering (diffusion). It is lower with clear sky and in the summer (45–48%).
kind regards

lk 2. Both of these, as far as I understand, use Open Street Map data which is WGS84. However when I superimpose the same area in Rhino I am finding they don’t match up.
Firstly I need to scale the data down by 0.001 presumably from km to m (or from m to mm???). And secondly, after the geometry has been scaled down, there is a discrepancy of 708.61m E/W and 217.52m N/S. There also looks like a slight rotation or scale difference.
Am I missing something? Since they both come from the same source and hence coordinate system, shouldn’t they align.

on't know if this is a bug in Rhino, RhinoCommon, Windows, MFC or .NET. What I do know is that that second event got absorbed by the slider, which in turn thought it had to start another solution. This second solution was running 'inside' the first solution and the two conflicted, resulting in a boat-load of identical error messages.
I fixed this issue (I think) by not responding to mouse-moves at all when a solution is currently running. I can find no more problems with the file you posted in this new setting, though there is quite a lot of flicker while dragging sliders.
You can reduce this by disabling the redraw while you're shuffling around breps:
doc.Views.RedrawEnabled = false;
Guid brepID = doc.Objects.AddBrep(b);
doc.Objects.UnselectAll();
Rhino.RhinoApp.RunScript(string.Format("-_SelID {0}", brepID), false);
Rhino.RhinoApp.RunScript(string.Format("-_Bend w{0} w{1} w{2} _Enter", coords(s1), coords(s2), coords(d)), false);
Rhino.DocObjects.ObjRef bakedObj = new Rhino.DocObjects.ObjRef(brepID);
A = bakedObj.Brep();
doc.Objects.Delete(brepID, true);
doc.Views.RedrawEnabled = true;
The fix with the recursive mouse-events will be available come the next release. In the meantime, you can try refreshing your solution by pressing F5, so you won't have to mock about with re-connecting wires.
