e case pictured already: don't bother how this truss is made and never mind that the def attached looks like an "add-on" (no components) - because it could be (so don't get stuck on that, it's irrelevant). In fact since the critical part (the 99% of the whole) if only doable with code ... it makes sense to do the rest with code as well (but that's my personal preference anyway, he he). Note: Balls are excluded from the demo.
You can toggle what "class" of struts is gonna being made with these booleans:
You can vary the sliders and if the code thinks that you make a valid input ... it obeys, he he.
But the big questions are:
1. Can you work with this in some interactive way? I mean vary any slider and ... wait ... for some change. Although the MERO components here are created ONCE and then placed around (minus obviously the tubes) ... they are placed as copies of the "donor" object (not instance definitions) creating a vast "pool" of "unnecessary" data.
2. What happens if you bake these little thingies? What file size you get? Is it OK?
But the bad news are that as I said ... this is ... NOT a task for a novice ... nor you can handle this get-a-truss-and-make-a-MERO-thing goal with half-measures: either you should do it properly ... or abandon ship.
NOTE: Load R file first (nothing is internalized).
Moral: even if this was made with components ... it wouldn't serve much.

H are automated by using them as an ActiveX, the C# script object fails on the simplest tasks. That is, when initiating Rhino and GH externally (as by the following C# code):
Rhino5Application rhino_app = new Rhino5Application();
dynamic grasshopper = newRhino.rhino_app.GetPlugInObject("b45a29b1-4343-4035-989e-044e8580d9cf", "00000000-0000-0000-0000-000000000000") as dynamic;
The following very simple C# script component fails because it cant cast its input:
The c# code at the component is only:
Line 89 is simply casting of the input. Clearly, this makes the usage of C# component, under automation, impossible which is a major loss.
As said, when initiating Rhino and GH manually , all works well as in the following:
Any ideas why it misbehaves under automation (as an Active X ) ?
I added the gh file of this example.…

I do not know how to load windows form and send data to object in form.vb...using grasshopper sdk.
it is the same,, when I try to use dll(class) with VB component in grasshopper.
may be I have to make two class (class1, form1) but,
when I send data to class1, form1 can not receive class1 data because form 1 made new class1 and both class1, class1(from form1) is different session?
for novice programer,, for me it is very hard.
load class1,
class1 load form1
send data from grasshopper to form1. x
and button click
couldn't calculated,... result was always "0"
and tried many other methods,, but it failed...
may be some known technic but it is hard to find books...
Please...help me.
if possible would you tell me how to load form1 using grasshopper sdk and ""send data "" to form1
or form1 could use data from grasshopper?
Thank you....
for ex)
'(in class.vb)
Public Class Class1 Private Shared fl As Form1 Public Sub fload() If fl Is Nothing Then fl = New Form1 fl.Show() End If End SubEnd Class
'(in form1.vb)
Public Class Form1 Public x, y As Double Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
ab(x, y) MsgBox("hi" & y) End Sub Sub ab(ByRef a As Double, ByRef b As Double) b = a * 2 End SubEnd Class
'(in Grasshopper VB.component)
Dim cl As ClassLibrary1.Class1 If cl Is Nothing And f = True Then cl = New Class1 cl.fload() End If Dim fr As ClassLibrary1.Form1 If fr Is Nothing Then fr = New Form1 End If fr.x = x a = fr.y…
le with you.
I am trying to achieve the minimal path algorithm of Steiners tree in Python using the minimal path algorithm.The syntax would be as followsFirst I need to create a cube of any dimension.
Then I need to specify one origin say point A and destination point say B.
Now for this point A,B I need to create a machine based network which will automatically enroute A to B.
Where the angle will be constant i.e 120, length can be a variable, triangular node(steiners tree)using these constraints it will create a network.
Now, I should iterate the program in such a way that I should specify the further points say like A1 and B1 so on.The program will contain a limit constraint where it will come out of iteration loop and start a new loop,forming the network.
By this I will get a dense network of 120 deg branches.
The branching gets denser the moment I add source and destination points.
There can be 100 iterations to reach from A to B but the algorithm chooses the one following the minimal path.
I would be highly thankful to you if you would please share the python syntax and grasshopper definitionCapture.JPG for the same
Thank you for your time in advance
I would be highly grateful if you help me through
warm regards

er, i hae drawn a quck sketch. Different curves in blue and orange colour. i have marked on my sketch which is a a non-planar surface.
At the moment, i have modeled this with NURBS curve component (component without Knots & Weights). I have set 5 to its 'P' intput (I'm going to reduce it to 3). Each point having 3 parameters X, Y & X axis. I have set my slider from -100mm to 100mm range. It is a closed curve.
If i just loft it, i get random results which i donot want. I can get a planar surface if i set Z parameter to zero. But how do i get a non planar and preferably a burbs surface?
the curves are very important to this projects. as Whole form is dependent on these curves.
Your tips will be highly appreciated. If you have different way of modelling it, I'm open to suggestion too.
cheers,

and perpframes
3) Ellipse on perframes
4) Series + Move + Series + Scale + Series + rotate (to create generations)
5) Divide curve (ellipse) + Dispatch only seleced points + join those points on ellipse using Intercurve + Divide the resulting intercurve
6) List items (I used list items 4 times, you could do as many). For 'i' parameter in list item i used slider to create generations. depending upon your definition, at this stage you might have to flatten your list output
7) joint the points you get from list output to form another intercurve + repeat that for all items.
8) Loft the curve
9) to form fenestrations, i again used rhino closed curves.
8) Project curve onto surface + copy trim + surface to mesh + mesh thickening from WB.
Hope this helps
Cheers

his project. Attached is my latest script. It seems to work for all points & directions of gravity except when the points are at equal height (in the reference plane the script creates, not in the world space). In other words, when the vector from A to B is perpendicular to the gravity vector, it doesn't work. It's totally due to the formulas used to solve for distance (see script), but I haven't found a way to fix it to make it work. Kudos to anyone that can help me figure it out!
Other notes: Required input: Point A, Point B, Gravity vector, and desired Height and/or desired chain/arch Length. Cool trick: when inputting both Height and Length, it recalculates the end point (point B) with those desired parameters, and the end point lies along the AB vector. Also, the "x" output shows either the found height, length, or distance (when both height & length are input), and "newPl" just shows the reference plane used to make calculations easier.

med that a 1000 lux measurement for a particular hour on a workplane grid point will indicate a illuminance from direct sun at that point. If I remember correctly, these simulations are to be run without the presence of any shading devices.
From an ASE calculation perspective, there are several shortcomings within Daysim (as it exists right now). The daylight coefficient method, which Daysim employs, calculates illuminance by dividing the sky into discrete patches. (http://naturalfrequency.com/wiki/sky-subdivision) For a clear sky with sun, the luminance from sun is accounted for by approximating the position of sun into 3 (as far as I know) patches. That in turn leads to an incorrect estimation of both position and luminance contribution of the sun.
Anyways, as I wrote in the begining, in my opinion the closest you'd get to calculating ASE from daysim right now would be running an annual daylighting calculation with Honeybee by setting ambient bounces as zero. A better approach, in case you are not trying to comply with something like leed v4, would be to do a DGP analysis as Chris mentioned in his post.

i projected my surface on XY plane, created voronoi curves on the planar surface and re-project / map the curves onto the subject model.
However, i'm not getting a desired result.
can any-1 please help me. or even show me a different way to model it via GH? I donot want to use rhino objects.
I have attached my initial sketch, GH and Rhino files.
Hope to find some solution so I could move forward :-(
Moreover, I could not convert the initial non-planar curves into surface hence I converted them into Mesh (thanks to 'Brian Harms' for helping me out). However, the protruding edges of the mesh is not a smooth NURB curve, it forms kind of vertices of a polygon. Any way to smoothen / fillet it? Will it affect when i commence 3D printing?
