No problem,

one thing useful is to put the RhinoCommon on the PC so no need to have internet. I put the rhinocommon.chm on my desktop/bureau of Windows. => upload next file

Thank you, it will help me !!

And do you know if there is the same thing for the general functions (except rhino) like list functions etc.

Hello,
How can I declare a global variable in the "runscript" that I can have in the functions without having to set them in parameter?

public double startX(Curve c, int tol)
{

return Math.Round(c.PointAtStart.X, tol);

}

and I would like :

public double startX(Curve c)
{

return Math.Round(c.PointAtStart.X, tol);

}

You can do that

private void RunScript(double x, object y, ref object A)
{
A = function(x);
}

// <Custom additional code>

double tol= 0.2;

public double function(double x)
{
return tol* x;
}

// </Custom additional code>
}

It works because it is inside a class, here  Script_Instance : GH_ScriptInstance

For the tolerance you can use

double tol = RhinoDoc.ActiveDoc.ModelAbsoluteTolerance

RhinoDoc.ActiveDoc.ModelAngleToleranceRadians ...

thank you

I managed otherwise by writing: (in Custom additional code). 
I could not find the syntax

private int tolerance;
private List <Curve> ATemp;

Do you know how to explode a curve or a polyline (for the c#)? (As the component explode of grasshopper )

I have been searching and I can't find

Use the seach in the chm file, or use CTRL+F in methods of Curve class and seek for explode

It must work for a type of curve,

1. polycurve => explode and 
2. Curve =>duplicatesegments (that means it is a polyline)

PolyCurve. Explode Method

Rhino 5 for Windows

Explodes this PolyCurve into a list of Curve segments. This will not explode nested polycurves. Call RemoveNesting() first if you need all individual segments.

Namespace: Rhino.Geometry
Assembly: RhinoCommon (in RhinoCommon.dll) Version: 5.1.30000.17 (5.13.60913.21340)

Syntax

C#

VB

Copy

public Curve[] Explode()

Public Function Explode As Curve()

Return Value

Type:  Curve[]
An array of polycurve segments.

***************************************************

Curve. DuplicateSegments Method

Rhino 5 for Windows

Polylines will be exploded into line segments. ExplodeCurves will return the curves in topological order.

Namespace: Rhino.Geometry
Assembly: RhinoCommon (in RhinoCommon.dll) Version: 5.1.30000.17 (5.13.60913.21340)

Syntax

C#

VB

Copy

public Curve[] DuplicateSegments()

Public Function DuplicateSegments As Curve()

Return Value

Type:  Curve[]
An array of all the segments that make up this curve.

Thank you !!

I had seen this function but how to convert curves into polycurve? I did not get there

Permalink Reply by Laurent DELRIEU on May 19, 2017 at 12:06pm

You don't really convert, you have to test the type of the curve 

see that :
