d work exactly as the physical model. In the model, we have a curved surface which can be analysed into squares. These squares are filled with two kind of units which are connected with each other and create a grid that follows this curved surface.
We have managed to analyse this curved surface into a planar surface consisted of squares and we painted the squares with colours to represent the kind of unit that "fills" each square. So, now in rhino I have managed to build the curved surface that I want it to be filled with the two types of units.
I also have the planar surface built in Gh with the squares split into two lists, each one for each kind of unit. Because these units are mambranes, I used kangaroo to make them act like mambranes.
I hope I described the problem clearly. The point is to keep the dimensions of the units
the same and make it work in Kangaroo. Do you have anything in mind that I should look up or any advice ? Thank you in advance and i m sorry for the extended description.

Thank you very much in advance!
1. why the underground zone representing the ground is defined as a plenum zone? By default, an office zone program is assigned. Will this affect the outside surface temperature of the ground plenum zone and affect, in turn, the outdoor microclimate map calculation?
2. I assume the construction GroundMaterial composed of five layers of 200mm concrete materials as assigned to the ground plenum zone is to assimilate a ground surface composed of thick concrete. But why this construction is assigned to this zone using both the Set EP Zone Construction and Set EP Zone Underground Construction components? Will the surfaces of this zone automatically recognized as underground surfaces based on their positions in relation to the default xy plane?
3. why a brep is connected to the input node distFromFloorOrSrf on the Indoor View Factor Calculator component which is expecting a number according to its annotation?
4. why the outdoor comfort analysis recipe is used for the indoor comfort analysis component?
5. why the OutdoorComfResult and DegFromNeutralResult are 2 csv files with PPD and PMV values if PMV/PPD thermal comfort model is only applicable to indoor air-conditioned space?

2. Modelo now supports VR! check out this video:
3. We've added a specular option in the rendering settings. So now you can have your design rendered a little bit shinny-er.
4. There is also a "filters" option in this panel, with which you can get some interesting image post processing effects. We are expanding this filter library, if you have any suggestions, please let us know.
5. This one is very important and has been requested by our customers for a long time. Now when you upload a model, you can grab the reviews(3d comments, screenshots,sketches) from your previously uploaded model! This works really conveniently if you use Modelo for your design review/presentation, cause you don't have to recreate the same 3d anchor views every time you made some changes to your design.
6. Also, our developer API is almost ready, which means if anyone is interested in developing a grasshopper plugin that works with Modelo, they can!
There are some many other updates and bug fixes happened. I don't want to list all of them here. Definitely stay subscribed with our newsletter. Modelo is thrived to grow into a more comprehensive platform! If you have any good ideas about our platform, please do not hesitate to let me know!
Here is our Youtube channel: https://www.youtube.com/channel/UCufBShhLtUQepsit9ilI-AA

the following image of a hut.
I do not have experience using kangaroo to simulate forces, but I have made a test using multiple random components on a flat surface to fake the effect I'm going for. See image below.
The main issue I'm having is that the original file used for my test surface used box morph and the variable pipe command. Box morph is a bit touchy on a curved surface and it is not as elegant as I would like it to be (ie. I want all the hair diameters to be perfectly circular and uniform in size). Variable pipe also does not align the base of the hair with the existing surface, which means I have to offset the surface and then trim the excess of my pipe.....leading to heavy code and the file crashing.
So I'm trying to rebuild the "hairs" using a new method:
1) Subdivide the surface
2) Find the midpoint of each surface and then create a straight line that is perpendicular
3) Move a point along the on the straight line (between the start and end points) in the z direction, and then create a nurbs curve using this point and the start and end points
4) create a circle at the base of each crv, and then two more circles: one at the point in the middle point (I think I set it to .9) and the end of the curve
5) The problem: Now I am trying to sweep along these three circles and the nurbs curve to create a bent hair/pipe that is flush with the conic surface, but it does not work.
If someone can help that would be amazing. I've included my original surface test file and my new file where I am rebuilding using the sweep command. Below is a drawing of what I'm trying to achieve.

he picture (4).
Previously, I had a problem with generating intersections between the two directions of the beams, but a colleague helped me by extending beams, so there was no problem with lines of intersection. But this solution has generated curl (5) at the highest vertex geometry, which I ignored in order to repair it before printing, perhaps this mean my problem with my beam spread properly. Only when the beams is 19, does not jump no problem, but I still can not distribute them properly.

o it would cause troubles with unfolding and fabricating... that's why I used Extrude point component- it will give you similar result, but all surfaces are planar.. you can control extrusion direction with a tip point in rhino...
2)I changed tagging so every tube has 8 points form list A and 8 points from list B... first number of tag is a number of point within one tube... last number of the tag is order of tubes (I draw a little picture in GH, hope you'll understand)...I think original way of tagging wasn't really usefull.. but you can change tagging by yourself...
3) the definition is really messy, sorry about that, but it's just quite complicated task...
4)if you find some incorrect order of tagging, use the slider that controls Shift List component ... it will shift tagging..
5) if you won't be using this definition or find some better way, pleeeease don't tell me - I'll jump out the window :D ... it took me whole day to make it work :D
6)I can't guarantee you anything- I hope it works, but if not - at least I tried... so check everything (especially order of tags and points) twice before you fabricate it.. or print few tubes and make them paper first..
7)there is a part of original definition, that is not useful anymore.. I left it there, but you can delete it (I called it "UNUSED PARTS OF ORIGINAL FILE")
..good luck

or create a form through code.
2) Add a public function to your component that displays this form, I recommend you use form.ShowDialog() for now to avoid weird conditions with non-modal forms.
3) Override the method Menu_AppendCustomComponentItems() on your Component and add an extra menu item that will show the form (i.e. when clicked, it will call the function defined in step [2].
4) Create a new class and derive it from Grasshopper.Kernel.Attributes.GH_ComponentAttributes. (if you don't want to offer double-click functionality, you can skip steps 4 to 6)
5) Override the RespondToMouseDoubleClick() method on the new attributes and also call the function defined in step [2]
6) Override the CreateAttributes() method on your Component class and construct an instance of the custom attributes defined in step [4] instead.
7) Once you've shown the form and the user has clicked OK, you need to assign values and invalidate the Component, then start a new Solution.
Here's some code:
Public Class MySpecialComponentAttributes
Inherits GH_ComponentAttributes
Public Sub New(ByVal comp As MySpecialComponent)
MyBase.New(comp)
End Sub
Public Overrides Function RespondToMouseDoubleClick( _
ByVal sender As GH_Canvas, _
ByVal e As GH_CanvasMouseEvent) As GH_ObjectResponse
DirectCast(Me.Owner, MySpecialComponent).DisplayForm()
Return Canvas.GH_ObjectResponse.Handled
End Function
End Class
Public Class MySpecialComponent
Inherits GH_Component
.....
.....
Protected Overrides Sub Menu_AppendCustomComponentItems( _
ByVal iMenu As ToolStripDropDown)
Menu_AppendGenericMenuItem(iMenu, "Set Values", AddressOf Menu_SetValues)
End Sub
Private Sub Menu_SetValues(ByVal sender As Object, ByVal e As EventArgs)
DisplayForm()
End Sub
Public Sub DisplayForm()
Dim frm As New MySpecialForm()
Grasshopper.GUI.GH_WindowsFormUtil.CenterFormOnCursor(frm, True)
If (frm.ShowDialog() = DialogResult.OK) Then
'Harvest values from form and assign them to local variables
Me.ExpireSolution(True)
End If
End Sub

sophy though, I have a rudimentary grasp of the Ancient Greeks and modern schools of thought such as Existentialism and Pragmatism, but there is certainly no depth in my understanding. However here the same rule applies. You can quote philosophy all you want, but unless you understand that which you're channelling you can be -at best- accidentally correct.
According to you, these are all vital characteristics:
Aesthetic judgement
Intuition about spatial effectiveness
Knowledge of construction materials & assembly systems
Consideration of performance-driven design properties
Mad synthesizing skillz
[1] and [2] are pretty much worthless, especially when we're dealing with students. Aesthetic judgement is not something that can be wrong or right. You can hone your aesthetic skills but you cannot cultivate better tastes. Intuition is also problematic. It's basically a stand-in for argumentation. Instead of saying "these buildings have to have 20 meters apart because of wind/sound/human perception/human psychology/light/shadow/etc. etc" is a far stronger statement than "these buildings have to have 20 meters apart because of my feelings". Who are you to be trusted? If you have a long and distinguished career backing you up, maybe your opinions carry some weight, but until that point you'd better be prepared to justify your decisions with cold hard logic and data.
[3] is certainly important for certain jobs in construction, but it can be argued that implementation details are not necessarily central to a design. One can design a good computer interface without having to be able to program, and certainly without being familiar with all the idiosyncrasies of a particular programming language. Conversely, one can design an excellent space without knowing exactly how strong certain atomic bonds are. If what you design is physically impossible, then obviously something has to change, but it doesn't mean that the design as an abstract idea was bad. Of course on the other hand one can argue that designing impossible things is not doing anyone any favours. I'm not exactly certain where I stand on this issue, probably comfortably in the middle; YES, students need to learn about what can be build in the physical world, but NO that is not part of design training.
I'm not quite sure what [4] means.
[5] is true for a lot of professions, not just Architects. I would concede that architects probably have more to take into account than most designers and that it is indeed an important skill to have.
I would say that -especially for students, who have little experience- an incredibly important skill to be able to ask yourself "why am I doing this?" about pretty much every decision you make. Basically you need to get very comfortable applying the Socratic method to everything you do.
