Hi;
Which friend cant give me a sample of this Method in c#?

@pythonuser, below pyton code might help to find out:

import Rhino
import scriptcontext
import rhinoscriptsyntax as rs
    
def pline_filter(rhino_object, geometry, component_index):
    if isinstance(geometry, Rhino.Geometry.PolylineCurve):
        return True
    return False
    
def DoSomething():
    poly_id = rs.GetObject("Select polyline", 4, True, False, pline_filter)
    if not poly_id: return

    mesh_id = rs.GetObject("Select mesh", 32, False, False)
    if not mesh_id: return
    
    polyline = rs.coercecurve(poly_id, -1, True)
    mesh = rs.coercemesh(mesh_id, True)
    intersect = Rhino.Geometry.Intersect.Intersection
    pts, faces = intersect.MeshPolyline(mesh, polyline)
    if pts.Count > 0: 
        rs.AddPoints(pts)
    else:
        print "No intersection points found"
    
DoSomething()

Think you @clement; in python I kown how to use it, but in c# I do not, because it mush 3 parameter in c#.

I am new in c# now:grinning:.
