def foo(mesh,dist,depth,iter):

    second_mesh=Rhino.Geometry.Mesh()

    vec_normal=System.Collections.Generic.List[Rhino.Geometry.Vector3d]()

    re_pts=System.Collections.Generic.List[Rhino.Geometry.Point3d]()

   

    for i in mesh.vec_normal:

        vec_normal.Add(Rhino.Geometry.Vector3d(i))

    for i in range(len(mesh.Vertices)):

        temp_point=Rhino.Geometry.Point3d.Add(Rhino.Geometry.Point3d(mesh.Vertices[i]),vec_normal[i])

        re_pts.Add(temp_point)

        second_mesh.Vertices.Add(temp_point)

    print(type(mesh.Facevec_normal))

    for i in range(len(mesh.Faces)):

        if mesh.Faces[i].IsQuad:

            ve1 = mesh.Faces[i].A

            ve2 = mesh.Faces[i].B

            pt_1 = re_pts[ve1]

            pt_2 = re_pts[ve2]

            mid_1 = Rhino.Geometry.Point3d.Divide(Rhino.Geometry.Point3d.Add(pt_1,pt_2),2)

            mid_1= Rhino.Geometry.Point3d.Add(mid_1,Rhino.Geometry.Vector3d(mesh.Facevec_normal[i]))

this throws the error:

  1. Exception occured in handler:
    No constructor matches given arguments: (<class ‘Rhino.Geometry.Collections.MeshFaceNormalList’>)
    File “.\app.py”, line 59, in mesh_ex
    mid_5= Rhino.Geometry.Point3d.Add(mid_5,Rhino.Geometry.Vector3d(mesh.FaceNormals))
    but what is wrong here? because I tried itin GHPython and it works perfect but now in HOPS it is throwing an error.
