of the topology) then with no degrees of freedom nothing will compute. I should add a check to identify and report this situation back to the user.
3. As few as possible quads isn't something I've dabbled in, I've put my hand a little to meshing, resizing etc but typically very specific circumstances when I've need to apply in particular circumstances. I just figure there must be mathematicians and programmers in various research/study positions that must be more knowledgeable than me in this area. If there is an existing algorithm/publication that I can enable into GH I'm happy to advise about enabling it for Grasshopper.
4. http://geometrygym.blogspot.com/search/label/Mesh%20Relaxation gives some indication of the example models etc that the force density tools have been developed in mind, also this project http://www.grasshopper3d.com/photo/albums/ballito-lifestyle-centre Typically this is akin to minimizing discontinuities in grids (British Museum Great Court Roof) or deriving equal mesh edge lengths. The output is a mesh, it can be exploded out to vertex and faces (or face edges). If you wish to create trusses, I'm assuming you want geodesics or similar? In an object with polar symmetry like yours, I'd tend to generate a single and rotate around. Do you have a sketch with what you desire?
5. The mesh routines only work with the subset of "untrimmed" nurbs surfaces, thus the number of useful applications is diminished. I haven't really coded this, although it shouldn't take that much time (it would compute an underlying UV mesh).
I hope this helps explain a little more, keep posting other questions and observations.

me screenshots of the Grasshopper's outputs after install.Same the 3 times I've retried : install 0.9.0006 / revert to 0.8.0066 that is still running ok ...
I've visited related places of the forum to get hints and it seems I am the only one to experiment the trouble!
at :problem-loading-grasshopper-with-rhino5-and-updating-scriptor : grasshopper-0-9-0005-available-for-downloadand from : grasshopper-0-9-0006-available-for-download, zipped downloaded gha's, no more duplicates found, but nothing that could resolve the failure of 0.9.0006 loading itself...
at : loading-error-unable-to-load-dll-rhcommon-c I run with latest vcredist_x86.EXE ...I am so exited to discover all those great improvements like vector fields stuff ...Thanks for help !…
the piece, that is mapped to the world XY plane & with as many parts as you define.
The definition is a sketch right now & so is not labeled so much, but the brep component at the left is where you reference the component you want to make a 2d of, then you use the slider labeled "Face#(percentage of # of faces)" to select the correct face(I think I can make a component that will automatically do this) , then adjust the X spacing of the 2d drawings, select the #Pieces, & bake the "Curves to Bake" component. Maybe it's a little involved at this point, but it's a start & beats doing all of that manually. This gets you the 2d of the parts you need to cut. Next would be a way to automatically generate the toolpath lines whether it's a "cutout"(being inside & outside of 'grouped' lines) or outside or inside cuts.
Then it would connect to your definition for defining feedrate, stepdown, end depth etc. + the g-code output.
I agree, a nesting program is not what this is about right now.
I actually think CAMel is along the lines of Lobster & Beaver - something more specific & involved.
That's why I'm excited about yours as a general plugin that can produce general 3, & eventually 4 & 5 axis G-code for production & cutting. I think with that platform working we can then tweak it or modify it to accommodate more experimental stuff. But for now, many need to be able to generate production code in a tightly integrated workflow like Rhino/Grasshopper.
A Rhino4 file in .zip format is attached that can go with the gh file.
Let me know what you think - maybe I'm miles behind . . .

lored meshes. (For some reason I have noticed that my windrose meshes always need to be flipped once they are baked).
You could go the long way, (as I droned on about in my previous post), and continue working with the meshes....or you could take Andrew's advice and do one or two more steps and bake them as colored hatches. That way you can export the results directly to an AI file.
(the attached definition requires ladybug/honeybee, human tools, and I think UTO mesh edit tools...not sure if the explode and deconstruct mesh components are native or not). I've attached the weather file I used.
Steps after the windrose component are as follows: (i'm sure there are other ways as well);
1- explode mesh (prepping data structure of color selection)
2a - decompose mesh faces to extract vertex colors (each face will have a number of vertices, in this case 4, that will all have the same color).
2b - get the outlines/curves of each mesh face
3 - use the SET component to "clean" the color values. (each face has 4 vertices, meshes are "colored" by vertices, so each faces vertices will be the same color. we only need one.)
4 - use Human tools to create color attributes from the cleaned, (with data structure in tact).
5- use Human tools create hatch using mesh face curves and color attributes. Bake into rhino, export as AI file.

ion of surfaces and/or "solids" : it's a very complex assembly of "components" either bespoke or widely available in the market. This demo combo summarizes the "common" cases (but the insulation for the opaque parts is WRONG 100%):
2. Contemporary trends (a bit of nonsense) point towards "liquid" forms. These ARE NOT made via "classic" linear systems. Very few actually can do it (I mean: do it yielding a building that doesn't leak]). Here's a totally wrong take on that matter from a very reputable Swiss facade maker:
And er ... hmm ... this :
3. Facade systems (curtain walls, that is) are classified in 4 classes: (a) the good old known humble stuff like the one shown in the first image (b) semi structural [yes], (c) structural [NO] and (d) planar frame-less systems.
4. Designing any proper facade is impossible with Rhino/GH: you'll need totally different software apps to do it - in real life - despite what most people believe/hope/wish.
5. Designing anything without a proper bottom-top approach (I.e. : first do the pistons then the engine) is the best recipe for not becoming (ever) a pro .…
omething:
2. Find all the curvy BrepFaces and do a variety or preparation work (for plan A or B):
3. Triangulate the curvy stuff as Mesh (Plan A: MeshMachine [ tricky], Plan B Ball Pivot on random pts + proper points on the "outer" Loop):
4. Make a classic MERO KK truss that supports the curvy thing and can easily host a reasonably cheep (and rain proof) glass facade.
5. Do a lot of other things in order to avoid clash situations (shown the "outward" truss option deployment):
Moral: less is more

m now enrolling in a research-based subject which its requirement is to investigate and write 5000 words of report or essay on topics such as arch history, sustainable arch , urban design and architectural computing.
As i am teaching myself GH , i have proposed to the unit chair of the subject whether it's possible to investigate and do a research on GH and use it as part of the unit assessment, and he is ok with the idea.
As I have never done this sort of research-based unit before , and never have a chance to sit down and talk the scope of works with him (unit chair). I am now a bit lost and need to come up with something, directionwise, before tomorrow night which is the last day to withdraw the subject.
It's impossible to contact my unit chair during the weekend and I would like you guys( which i think some of you are academic people or lecturers) to suggest me on
1. What's scope of work should my research cover , it's a 10 weeks and 5000 words projects , in my case it could be less given my result would be some images as well as the report ?
2. My initial thought of the topic and the result of this research would be
what is GH
how to use it......go through some basic operation ?
the result , create and illustrate the complex form that GH can produce , images of model
other application .....
3. I am interested in voronoi diagram , is it possible to investigate this and maybe come up with some voronoi forms for my final submission , is 10-11 weeks enough ?, given that i've only known GH for 2 months and never learnt voronoi before. It's too ambitious isnt it.
4. Given that my resource would be mainly from internet , what is the possibility of this project get done in 10 weeks ?
5. Any suggestion.
Thank you very much

to Daniel Pikers' Tutorial mesh relaxation tutorials we are already pretty far.
The Idea of our design is a hanging structure suspendend in a gap between buildings, where you can find places to rest, read or even to sleep. You can find privacy in the cocoons, that are connecting the planes with each other.
As structure we have a net in mind, that is tighter in the area of the cocoons and more transparent in the common areas, but we really don't know whats the right way to get to this point.
In the end of the project we need a printable geometry. We start our boxy design in Sketchup, and remesh it in Rhino. After that we feed it in our kangaroo definition.
1. A nurbs surface could give us more freedom (for postprocessing in tsplines) to form meshes with shorter and longer edges, representing our net. But I see now easy way to get a surface out of the relaxed kangaroo mesh.
2. Working with the kangaroo mesh could also work fine, if we'd find a way to control the edge length of the mesh (for example 20 cm in the common area and 5 in the privates) with an attractor point. Remeshing with Daniel's Plankton Plugin sadly doesn't work, I always get the "runaway faces circulator"-error.
3. It woud be great to convert the mesh to a hexagonal mesh, but I don't know any possibility to remesh an existing one...
You see, we're full of questions, but I really hope to get some help here :)

nfusing.
Problem 01: the requested in-put of 'CroSecs' from 'OptiCroSec' component, based on introduction of itself, "a list of preferable structural thickness", and the algorithm will automatically find the sufficient number as the beam thickness. BUT, when I plugged 3 ranges, 1 to 15 CM, 2 to 15 CM, 5 to 15CM, the algorithm will always choose the finest number as the beam thickness, which turns out the beam thickness is, 1CM, 2CM, 5CM. 5CM in reality 'maybe' correct, but I just cannot image 1 and 2 CM beam will work. That`s very confusing.
Problem 02: the 'MaxDisp' from 'OptiCroSec' component, no matter how I slide the number, shape will remain still always. what is the fucntion of this input, should it be like a control to deformation of the shape?
Thanks in advance for any insight you can give!!
I attached 2 images to show the problem 01, and in the file rhino and gh, i marked out the problem part with red panels.
Best wishes,
Lei

yet accessible features that have been well factored.
I’m impressed with the mainline experience overall. BUT, and this is a huge but, Rhino5 has an absolutely massive bug right in the middle of the engine. I, of course, refer to the Boolean Problem. I’ve put the product down cussing 4 times already after realizing that I’d just lost 3 hours trying to figure out why something doesn’t work, only to realize that I’m up against yet another derivation of The Boolean Problem.
I’m written McNeel tech support about the issue. They’ve offered file-specific workarounds in response. But these workarounds don’t allow a solution that can be used resolve generalized characterizations of the bug in Grasshopper programs. Brian, the support tech I’ve dealt with on this problems goes on to say that I shouldn’t expect any significant fixes for this problem.
I’m shocked that major revision 5 of a seemingly mature product as Rhino is has such a gigantic, mainline bug in the very core of its engine. But even more surprising is Brian’s suggestion that perhaps I’m just not ready for a product like Rhino. He further suggests that I post, as I’m doing here, to see what other people think about this bug.
So what am I missing? Where do experienced Rhino/Grasshopper users find themselves on the continuum between this being a big hairy bug that should have been fixed long ago and my just not being ready for Rhino?
I’ll accept any input and consensus that prevails.
