NetworkSrf, C# and Rhino SDK

Greetings,

I am working with Grasshopper and I am trying to make a script that creates a network surface and returns it to Grasshopper.

Marc Hoppermann made a similar one befor but it is outdated. http://www.grasshopper3d.com/forum/topics/network-surface

At the moment, I am working with C# and got some problems understanding the new SDK of Rhino.

My question would be:

Is there a way to change the “AddCurve” command in line 2 so that it returns a Curve (type)?

Or do I have to work with Guid and if yes, how can I select them and add them to a list?

1 foreach (Curve Crv in CrvList) {

2 Curve bakedCrv = doc.Objects.AddCurve(Crv);

//doc.Objects.AddCurve(Crv) returns type Guid, but I need type Curve

3 bakedCrv.Select();

4 ListOfCrv.Add(bakedCrv);

5 }

Thank you very much.

Max

Hi Maximilian,

Can't help you with your current problem, but at the time when that topic was created (2009), there was no RhinoCommon method for creating a surface out of curves network. Since then, at some point it has been implemented:

There's a simplified version, and the one with control of curve parameters for both directions.

Sorry, Why do you want to bake anything?

Network surface is now in the sdk and as a component.

private void RunScript(List<Curve> C, ref object E, ref object S)
{
    int error;

    NurbsSurface Surf = NurbsSurface.CreateNetworkSurface((C), 1, RhinoDoc.ActiveDoc.ModelAbsoluteTolerance, RhinoDoc.ActiveDoc.ModelAbsoluteTolerance, RhinoDoc.ActiveDoc.ModelAngleToleranceDegrees, out error);

    S = Surf;

    switch (error)
    {
      case 1:
        E = "Curve sorter failed";
        break;
      case 2:
        E = "Network initializing failed";
        break;
      case 3:
        E = "Failed to build surface";
        break;
      case 4:
        E = "Network surface is not valid";
        break;
      default:
        E = ":)";
        break;
    }

}
