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)

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.

ctor. I do not dispose of any IGH_Goo instances, mostly because I have no idea when an instance is truly no longer needed. If any of your fields need to be disposed, you may have to implement a destructor, but I have no experience with this.
2) should I pass those classes to other parameters by DA(0, MotherClass.Duplicate?) or it is already there by GH_Goo ?
IGH_Goo is not duplicated by default. If you use DA.GetData() and ask for IGH_Goo types, you'll get a reference to the same instance as exists. Thus, if you take in an instance of your type, modify and output it, you should duplicate it yourself. But you only need to do this if you change the state of an instance.
MyGooType data = null;
if (!DA.GetData(0, ref data)) return;
data = data.Duplicate() as MyGooType;
data.Property = newValue;
DA.SetData(0, data);
3) should I create ChildClass and MotherClass in SolveInstance, or create it once as a component's field and then change theirs properties and pass it to DA (as duplicate ?)....
It's almost always better to use variables with the lowest possible scope. So method variables are preferred to class variables, class variables are preferred to static variables.
4) if I create those classes in SolveInstance, is it necessary to Dispose them there ?
NO! Do not dispose of instances that are passed on to output parameters. Disposing objects typically makes them invalid, so if you share instances with anyone else, you should not dispose them or the other code may well crash. However I don't think your types need to be disposable so this is a moot point now.
In general, if you're dealing with disposable types, and the instances aren't shared, then you dispose them as quickly as possible. But if they are shared it's a lot more complicated.
5) finally - maybe it would be better if MotherClass inherits the ChildClass ?
Maybe. Not necessarily. Depends on the classes. …

On the other hand ... well ... we can pretend that this could be some sort of add-on dedicated for broken pieces, (and nerves if loops = a big number) he he.
Anyway:
1. If you enable the history (the yellow things) you can watch the recursion working: get a donor box and "slice" it in 2 (either via an "orthogonal" plane [the fast boxes] or a random one [the slow breps]). Then get each one and repeat until the desired "depth" of "slices" is achieved (the loops, that is). Pure recursion in terms of programming (a function does something, yields results and then calls itself to further process each result).
Double click on the C# to see the code (but don't change anything). For the record this is the function that does the main job (spot the fact that if it's not terminated it calls itself [last line]):
2. The x, xy, xyz options restrict the random plane (actually in the boxes case there's another technique used (Intervals) but never mind). For instance (case random breps) the slicing plane is defined at the brep center and using a random direction:
Vector3d dir = new Vector3d(rand.NextDouble(-1,1), rand.NextDouble(-1,1), rand.NextDouble(-1,1));
If the 3rd value is 0 then the plane's YAxis is parallel to Plane.WorldXY.ZAxis.
3. Now if the "slicing" thing was a random polyline at a random plane the pieces could be far more "elaborated" (and/or "naturally looking") ... but the thing with programming is to know(?) where/when to stop.
4. This approach could use any donor Brep (a blob for instance) or a Brep List. Notify if you want to add such an option.
5. Added some lines more for an option that allows to sample the pieces (due to the last loop) in an automated flat "layout" (it's a bit more complex than it appears on first sight).
6. The x,y restriction mode now affects the random slices as well. See what I mean:
and the same restriction using boxes:
Truth is that all that freaky stuff could be helpful for you if you had serious plans to learn C# (not something achievable without pain and tears aplenty).
best…
e point in each pair that has the lowest Z value (then later the highest Z)... The problem is the intersections are not returned sorted by Z, sometimes the lower point is first in the list, sometimes last. So I need to sort those pairs of points by Z value.I noticed the sort points component does not have any inputs for sort criteria... RhinoScript SortPoints allows you to sort by:
blnOrder
Optional. Number. The component sort order, where:
Value
Component Sort Order
0 (default)
X, Y, Z
1
X, Z, Y
2
Y, X, Z
3
Y, Z, X
4
Z, X, Y
5
Z, Y, X
Will we get something like this in GH? For now I think I can manage to analyze the Z for each and re-order the points, but a more comprehensive point sorting tool might be nice... no? Or did I miss something obvious? --Thx, --Mitch…
n due at the end of march. i am hoping to see if i can do this as a sort of "HIVE MIND" experiment with one or two or more posters to the forum. i have uploaded two files to http://www.formpig.com/nine_bar-FAR and I have the following goals:
1. To "kinematically iterate" various formal building envelopes based upon a 50' x 100' lot that "conform" to the nine bar linkage geometry.
2. This lot would have "setbacks" consisting of two 5' side setbacks, a 10' rear yard setback and a 25' front yard setback. max height on the structure is 32' and the allowable overhangs into the setbacks are 2'. I would like to find a way to use the "nine bar geometry" to construct a series of iterations for "floors", "walls" and "ceilings", which would then be tied to a volumetric (cubic volume), or a total square footage (perhaps based upon two horizontal section cuts) which was based upon a given number that I will provide per local building code.
3. Laid on top of this we would also have "mcmansion ordinance" requirements based upon the pdf enclosed. i expect to have this "tent restriction" data in digital form to upload to ftp shortly.
It would be up to you individually or collectively to determine how best to position this "in the real world" based upon the lot, setbacks, zoning requirements etc. For instance, perhaps the nine bar configuration has its vertices coplanar with the 50' x 100' x 32' envelope restrictions and then the chosen volume is "trimmed' by the setback requirements. Or perhaps the nine-bar configuration is generated completely within the setbacks, or perhaps it is generated 2' outside of the setbacks so as to take advantage of the 2' overhang allowance on the setbacks, etc.
*
Given an opportunity to develop the work in a second phase we would have an opportunity to tie this into various efficiencies such as Bill of Materials (wall floor and ceiling square foot calculations), envelope to volume calculations, solar panel efficiencies (solar orientation and envelope geometry) etc, etc (love to get suggestions for this).
*
I've become /really/ convinced that this would be a /really/ interesting entry based upon my just finishing up Kas Oosterhuis' Towards a New Kind of Building: A Designer's Guide for Non-Standard Architecture". In an ideal world I was hoping that it would be possible to hash this out discussion-wise and then literally passing it around on the list after someone eventually made the first move by tossing out a rough ghx script. My expectation would be to finalize it rapidly in the next two weeks. Something of a contemporary version of a design charette.
However, I realize this may not be workable so if you have experience in this arena and particularly if you think this is a brief that is straighforward enough to be almost literally implemented in Grasshopper, please contact me for any wage and/or contract fee requirements.
I'm getting a bit of a late jump on this but my hope is that with the right participant(s) that I can thrash it together quick enough for the first round.

case for sure (started by Giorgio a couple of days before). Ive got involved because I exploit ways to "relax" shapes on nurbs (say patterns created by Lunchbox or "manually) without using any kind of mesh (more explanations soon).
Here's 5 test cases (SDK appears that doesn't have some "thicken surface" thing ... thus the algo that finds the "whole" shapes is rather naive) VS 2 Kangaroo "methods" and the why bother (he he) option as well.
If the goal is to "fit" these shapes within the nurbs ... does it work so far? No I'm afraid (appears that "springs" used are not the proper ones - or [Kangaroo1 option] the lines that pull should been originated from valance 2 points only)
Tricky points:
1. Internalize appears having a variety of serious issues (see Input inside definition) - Load Rhino file first (but even so ...).
2. Pull to surface is deactivated - this is not the issue here (and it's very slow).
3. Since Starling/WB alter the "curves - points" related order
the issue here (Pull points to curves) is to correspond apples to apples:
and that's what Anemone does:
From chaos :
to order:
this means that prior activating Kangaroo you should double click to the Anemone start component in order to "sort" properly the curves.
But .. fact is that results are pathetic:
more soon
