Hi everyone,
I was doing the ICD-Course from 2017 today and tried to make some changes,where the problem occured.

I have a class relying on the standard Grasshopper template to harvest the values from Grasshopper and than pass them to another class.

I am getting the Points read in correctly, but when I want to use them in the other class, the list comes in as null.

I cant understand how to assing the List correctly?

Thanks in advance!

Hi all

I have a general question regarding ‘Multitreading’ in a C# component.

In one of my recently-developed plugin components I’ve replace some ‘for loops’ with the ‘parallel.For loop’ alternative using information that I’ve found on the following webpage by James Ramsden: http://james-ramsden.com/multithreading-a-foreach-loop-in-a-grasshopper-components-in-c/

This seems to work great as you can see my component speed is several orders of magnitude faster now: (This example was performed on a pc with 24 cores)

So now my question: What are the differences / disadvantages comparing this techniques with the ‘IGH_TaskCapableComponent’ interface. Information here: https://developer.rhino3d.com/guides/grasshopper/programming-task-capable-component/

Should I remove the component that is single threaded from my plugin with release? Or will some users prefer not to use multithreading? Should I combine both and use ‘AppendAdditionalComponentMenuItems’ to let the user decide. Or should I look further into making a TaskCapableComponent.

Thanks in advance for any comments!
Kind regards

Hi all,

I have a simple question: I want to access the value of a enum by using an integer as for example in the curve extension method:

public Curve Extend(CurveEnd side,double length,CurveExtensionStyle style)

I want to use it like:

Q : When I type numbers inside numericUpDown slides and click “Apply” button, the numbers are imported inside the grasshopper parameter, “That’s a great news !!”. However, Whenever I saved the grasshopper file, closed the rhino file, and then reopened the rhino and grasshopper file, the numericUpDown values, and the values inside the grasshopper parameter are reset.

But I want to persist all these numbers after I click “Apply” button and save the grasshopper file.

How can I solve this problem??

[[EDIT: SEE SECOND POST]]

Hi All,

Here’s an easy one that is a C# problem not a Grasshopper one - per se - but I’ve been banging my head on it and your GH specific advice would probably break the logjam more quickly than I’ve been able to.

The question, put simply, is how do I index with [] on a method group?

I’ve followed this tutorial and it works well for packaging up the data and sending it to the next component using GH_ObjectWrapper.

So here’s the relevant code snippet:

    internal static GH_Structure<GH_Point> CellRootNodesArrayBased()
    {
//  A class containing data describing the whole lattice - generated upstream
        Lattice l = new Lattice();

//  A class containing attributes of an individual cell of the lattice - generated upstream
        LatticeCell lc = new LatticeCell();

//  A string describing the cell "centering" 
        string classCentering = lc.Centering;

//  DataTree of the cartesian locations of the points
        Grasshopper.DataTree<double[]> nodeTree = l.LocationTree;

//  DataTree containing lists of paths to the points within the lattice which describe the 
//  vertices of a cell. 
        Grasshopper.DataTree<GH_Path> lCIT = lc.CellIndexTree;    

//  THIS LINE IS WHERE MY ERROR IS HAPPENING               
        GH_Path localPath = lCIT[(lCIT.Branch[0]),0];

//  Local Root Vertex – the point to be determined from this program and inserted to a tree to be passed
        GH_Point lRV = new GH_Point();

//  NOTE, this code for the assignment of values to the points is all old, 
//  based on looking up x,y,and z from a 3 element array that was on a list. 
//  This will change based on the syntax to access the proper branch of the tree I’m 
//  asking for your help on above, but I wanted to include it so you understand the goal. 
//  Obviously I need to be able to access the right Branch {x;y;z} before I access the right 
//  list item (double[3])and element of that array.
        var p00 = new Point3d(lCIT[0][0], lCIT[0][1], lCIT[0][2]);
        var p06 = new Point3d(lCIT[6][0], lCIT[6][1], lCIT[6][2]);

//  I creates a point at the center of the cell
        if (classCentering == "I")
        {
            var p14 = (p00 + p06) / 2;
            GH_Convert.ToGHPoint(p14, 0, ref lRV);
        }

        else
        {
        }

//   lRVT = Local Root Vertex Tree
        var = new GH_Structure<GH_Point>();
        lRVT.Insert(lRV, localPath, 0);
        lc.RootVertexTree = lRVT;
        return lc.RootVertexTree;
        }

So obviously, I’m getting “no argument given” errors re: the path in the point creation. Once I fix the big problem that’ll sort out.

The one that’s tripping me up is "Cannot Apply indexing with [] to an expression of type ‘method group’ on the line where I assign a value to localPath from the (local) Cell Index Tree, which is referenced in from the class Lattice Cell, which has been invoked locally as lc.

The core issue seems to be just a simple syntax mistake, and your patience and help is very appreciated.
Thanks in advance!

If I don’t input any parameter in “I”, my component won’t work.

But I want my component to still can work if I don’t give any parameter in “I”. How to do that in code?

Dear all,

Is there possibly a way to use GH_CustomPreviewItem for previewing (DrawViewportMeshes) of custom components made in Visual Studio?

At this moment I’m stuck because of the “inaccessibility due to the protection level”. I would like however to manage the preview of all sorts of geometries without manually sorting them into groups (GH_Curve, GH_Mesh, GH_Point…) Additionally, the preview as executed by the CustomPreview component in Grasshopper is very slick and allows a rendered preview as well. I would like to go along with this approach if possible.

the error message in English is:“Only one usage of each socket address(protocol/network address/port) is normally permitted “.
i use “netstate -a” to check the net socket usage ,i am sure every time the “59153"port is available to use before launch Rhino and grasshopper.
so I go to debug ,i add a break point at"udpClient = new UdpClient(localPort);”,then i find when this breakpoint is hit, i see the udpClient is null and then be given a newUdpClient(localPort) ,it is i want and nothing error happens when be given a newudpclient.so in normally,the solveinstance() should stop after " DA.SetData(“UDPClient”, udpClient);”…but no…when i press continue …the program stop at breakpoint second time!,so udpclient is null again!(it should be not null because already has been set),and it will be given again with same portNumber,this is the source of error"collision of port”.
I just donnot know why the solveinstance run twice …
(and i found solveinstance sometime run one time,and sometime run twice…)
Thank you for explain!

Hi guys I am new to grasshopper and after some advice. I would like to be able to create lines coming from a known point let’s say 0,0,0 in the centre of a dome. I would like to specify the spacing of the lines but it’s probable going to be every 5 degrees in the Azimuth and Elevation. I would also like to be able to specify the radius of the dome. I would then like to intersect the lines with the sphere to produce points on the sphere itself. So, I will be left with a point cloud effectively on the dome surface every 5 degrees. It would be even better if I could specify the angle of the dome to so I can switch between a partial dome and a full dome.

I am sure its easily achievable but my knowledge is zero currently with Grasshopper so any help would be appreciated.

thanks

Hi,

@DavidRutten I have an issue with grasshopper plugin loading. The plugin works on some windows computers and on some not, with the same newest rhino installed.

It is not possible to debug the component, since the grasshopper gives error while loading grasshopper below, and wont load the half of components.

I quite sure that is because of some file directory issue, but not sure which line of code is causing that.

Any suggestions how to debug components at the start of Grasshopper would be much appreciated.

The error while loading:

    Object: ComponentDrilling (level 1)
    {
      Exception has been thrown by the target of an invocation.
      TargetInvocationException
    }

    Object: ComponentDrilling (level 2)

      The path is not of a legal form.

    }

Hi,

sorry if this has been asked before – but I could find any working solution.

Is it possible to call a external script, (python or .bat) form within Grasshopper? Ideally while passing arguments and output of the script.

I have a param in a component that’s adding a “Remark” runtime message. The component is also adding a “Warning” runtime message. I would expect the component to be “warning” orange — but because of the presence of the “Remark” it looks normal hunky-dory gray. I would expect the precedence to happen Error > Warning > Remark in terms of setting the component color, but it appears to be Error > Remark > Warning. But maybe I am misusing “Remark”?

Struggling to understand how to make a custom geometry draw mesh wires when Grasshopper’s -Preview Mesh Edges- option is enabled disabled.

I assume there’s some line of code I need to add into one of the draw methods in the GH_GeometricGoo class, currently mine looks like this:

public void DrawViewportWires(GH_PreviewWireArgs args)
    {
        if (Value == null || !Value.IsValid) { return; }

        if (args.Viewport.DisplayMode.EnglishName.ToLower() == "wireframe")
            args.Pipeline.DrawMeshWires(Value, args.Color);
    }
