Our control cage structure actually allows for the deletion of points from the control cage structure. However, in rhino when I select grip(s) and tap delete, nothing happens (which is to be expected)
What is the easiest way to allow rhino to call a method in my CRhinoGripObject or CRhinoObjectGrips subclasses when the user tries to delete a grip?
I tried implementing IsDeletable with no effect.

I’m not talking about CRhinoGetObject, I mean select objects as if user had clicked on them.
Closest I can find is this post Select object from code, which talks about C++ being able to do this, but provides no specifics.

Helo
in the documentation API : https://developer.rhino3d.com/api/RhinoCommon/html/P_Rhino_RhinoApp_MainApplicationWindow.htm
i read :
[ObsoleteAttribute("Use MainWindowHandle or RhinoEtoApp.MainWindow in Rhino.UI")] public static RhinoWindow MainApplicationWindow { get; }but where is the RhinoEtoApp.MainWindow documentation ?
thanks.

ApplyLightChanges is not called when the layer on which a light is placed is hidden.
I don’t know if this is at all related to the changes you are about to make to the change queue (see my other post here Problem with ApplyMeshInstanceChanges and linked blocks) so I opened a new thread.

Hi,
I would like to ask how to retrieve multiple curves, and append to C++ collection only valid ones.
Essentially my simple question is what Collection type I should use to add valid curves when I do not know the fixed length of collection?Second question: to retrieve all selected objects I have to write:
go.GetObjects(0, -1); ?For example here I retrieve curve objects from rhino and if they are valid I would like to add them to a collection.
CRhinoGetObject go; go.SetCommandPrompt(L"Select Curves"); go.SetGeometryFilter(CRhinoGetObject::curve_object); go.GetObjects(0, -1); if (go.CommandResult() != CRhinoCommand::success) return go.CommandResult(); //What kind of collection I should declare here <--------- for (int i = 0; i < go.ObjectCount(); i++) { //Get first object + validate const ON_Curve* crv = go.Object(0).Curve(); if (crv == 0) { return CRhinoCommand::failure; } else { //Question---------> add to curve list; } }

Hi,
I would like to merge several connected ngons into one.
Before doing that, I expected I could remove several existing ngons ones, and then create new ones.
But when I print how many ngons are before and after removal I get the same number.
What would be an approach to my problem?Rhino.RhinoApp.WriteLine(mesh.Ngons.Count.ToString()); //Prints 55 mesh.Ngons.RemoveAt(1); Rhino.RhinoApp.WriteLine(mesh.Ngons.Count.ToString()); //Prints 55

This one is very tricky. It may not make sense for how rhino works, but it makes sense to me and definitely for the UX of how I want this plugin to function.
I have a multitude of problems with the code the way I have it working below. My questions/issues are below the code listing.
CRhinoGetPoint gp0; gp0.SetCommandPrompt(L"Select Pull Origin"); gp0.GetPoint(); ON_3dPoint origin = gp0.Point(); CRhinoGetPoint gp; gp.SetCommandPrompt(L"Select Pull Destination"); gp.SetBasePoint(origin); gp.DrawLineFromPoint(origin, TRUE); gp.GetPoint(); if(gp.CommandResult() != CRhinoCommand::success) return gp.CommandResult(); ON_3dPoint pt = gp.Point(); ON_3dVector v = origin - pt; //if(v.IsTiny()) // return CRhinoCommand::nothing; //you've got to be kidding me.... //ON_Xform trans = ON_Xform::TranslationTransformation(v); for(int i = 0; i < translationTarget.Count(); i++) { translationTarget[i]->SetPoint(translationTarget[i]->Point().point+v); //context.m_doc.TransformObject(translationTarget[i], trans, true, true, false); } auto surfacedObj = dynamic_cast<CRhinoSuperDGrips *>(newObj->m_grips)->NewObject(true); if(!context.m_doc.ReplaceObject(CRhinoObjRef(newObj), surfacedObj)) { OutputDebugStringA("there was a problem"); } context.m_doc.Redraw();First, is there a way to not make the user laboriously click two points to get my translation, but instead to simply drag the screen in one swoop?
Second, do I really have to update my rhino grip points one by one? translation via TransformObject didn’t work. This isn’t a big deal but… it’s quite cumbersome.
Third, related to the second issue, when I drag the points on the upper left viewport, the Y & Z directions seem to be swapped, likely due to a difference in coordinate systems between grip point and return values from the GetPoint

Hello,
If not have time skip to bottom with the list of items 1 2 3. Can I do these in python?
I have picked up Python and have been writing some scripts for Rhino in the last few weeks and I really like how all works in Python.
I would like to ask what more experienced programmers think, if I can stay in Python (and not learn a new language) for the things I want to program.
I want to manipulate meshes.
Selecting vertices, edges, faces, mainly modifying the geometry based on criteria for each of the selections.As an example, looking at this page (below), I see that under syntax, there is only C# and VB listed.
Is it possible to access these features with Python?What I would like to work on is create a set of tools for me, to help me manage very specific terrain and landscape design tasks. And so modify quite low definition meshes in specific ways to suit my design needs.
I am mixing design and art thinking here with my coding skills and I want to write something like an algorithm that will help aid and generate designs based on very specific meshes that I will create most likely in blender or perhaps 3ds max (as I already have good skills there) but from there to work entirely in Rhino.Few examples of small tasks that I can think of at this initial stage:
I would have data points of coordinates (locations) in 3d space. Take these coordinate datapoints, and to each, add a (spherical ?) bounding area. Then take a mesh and go through each edge. If both vertices of an edge fall within any two of the initial coordinate “spheres” then add these edges to an array that I can use to select them later.
In short I am going to use one basic mesh to extract the datapoints and later use these points as a selection aid to apply to another mesh.If I do not have sufficient faces in some areas, can I easily use a selection of edges to split them the way “split a mesh edge” does (the sizzors icon). So basically just dividing each of the selected edges in two.
Can I extract info about two faces of a mesh, lets say how big a face is, how many edges does it have etc, while pointing to these two faces by giving an input of the edge that is dividing them.
Thanks for reading and for eventual input I might receive from this essay : )
Main question is if I can do all in Python.
Secondary would be any advice of where I can begin… the first 1, 2 things that will get me rolling with this.Thanks

Let me preface this by saying F# and c# are functionally equivalent. I’m interested to know if there are any F# RhinoCommon devs who could weigh in on the pros and cons of using F# the F# way? Like the performance gain through ease of concurrency vs the loss from memory allocations due to the default of immutable variables.
I’m currently trying to parse through some c# I wrote years ago, and I’m reminded of all the purported benefits an F#. The conciseness, functions as parameters, piping, etc. of F# is in line with what I’m doing. I don’t want to build a library of objects. I’m building a library of functions to augment Rhino’s library of objects.

I’m trying to integrate an external program I’ve written via calling a new process. I’m using python to call the program from within GH. I’d like to get some quick visual feedback on the state of the output and one way I’d thought of is to change the colour of the connected panel. At some point I saw somewhere that you could access the inputs and outputs of the current component, but I can no longer find the example. So ideally what I’d like to do is change the color of the connected output panel. If there’s no errors, set the shown panel color to green, if there are errors, set it to red. Is this possible, or am I barking up the wron g tree? Any help greatly appreciated.

Hi,
When vertices become topologically identical?
Is it somehow connected with tolerance?
int[] tv0 = mesh.Vertices.GetTopologicalIndenticalVertices(v0);The reason for asking is that for cylindrical surface mesh subdivision I get 4 identical points, while same surface with some distortion on he right has only two topolgically identical points. (no gaps at surface edge)
And this tolerance issue results only on at the edges of surfaces, when I detect closed surface condition I reset end points to start ones:

Any idea why, am I approaching this correctly?

Hello All,
I am making Surfaces from a list of edge curves.
I seem to be getting unpredictable UV directions for my surfaces.I though that the UV would be determined by the order and direction of the list of curves.
Is there some other factor that I am not considering?Currently, I have my list of curves setup as follows:
Curve[0] ends at the start of Curve[1]
Curve[1] ends at the start of Curve[2]
Curve[2] ends at the start of Curve[3]
Curve[3] ends at the start of Curve[0]I pass that list to Brep.CreateEdgeSurface(curves).
Sometimes the UV is as expected, sometimes it isn’t…I am thinking about comparing the resulting UV corner points of my surface to check if they match my Curve Endpoints then flip/transpose as needed to make the correct adjustments to the surface.
Is there a better approach? I haven’t found any details on how the List of Curves makes the Surface.
Any advice or examples would be greatly appreciated!Kind regards,
Jake

I tried using CRhinoGetOption but its Option() method immediately fails no matter what I add to it.
