Incrementally rotate a line using VB.net, C# or python

Hi Guys,

I am trying to incrementally rotate a line using the codes below in c# and Vb.net. The components show no error but they only overlap lines...Any idea what is going wrong? The python attempt just gave the strange message "i" unexpected token "i".

Many thanks,

on C#:

Arthur

private void RunScript(Curve ln, int x, double angle, ref object A)
{

List<Curve> lines = new List<Curve>();
Int16 i = default(Int16);

for(i = 0; i <= x; i++){
ln.Rotate(angle * i, Vector3d.ZAxis, ln.PointAtEnd);
lines.Insert(i, ln);
}

A = lines;

on VB.net:

Private Sub RunScript(ByVal ln As Curve, ByVal x As Integer, ByVal angle As Double, ByRef A As Object)

Dim lns As New List(Of Curve)()
Dim i As Int16

For i = 0 To x
ln.Transform(transform.Rotation(angle * i, vector3d.ZAxis, ln.PointAtEnd))
lns.Insert(i, ln)
Next

A = lns

in python I get the strange error : unexpected token "i"

For i in xrange(0,x):
rs.RotateObject(angle * i, vector3d.ZAxis, ln.PointAtEnd)
rs.AddLine(lns)
A = lns

Hi Arthur,

there were some minor syntax mistakes but one big issue: you should remember to copy objects if you do not want your changes to be not propagated from one tranformation to the next one.

(I've added a rhinoscriptsyntax and a RhinoCommon version of the Python script. Rhinoscriptsyntax works in degrees).

Thanks,

- Giulio
