Hi

I am trying to run the following code in PythonScript:

Source: https://developer.rhino3d.com/samples/rhinocommon/add-radial-dimension/

from Rhino import *

from Rhino.DocObjects import *

from Rhino.Commands import *

from Rhino.Geometry import *

from Rhino.Input import *

from scriptcontext import doc

def RunCommand():

rc, obj_ref = RhinoGet.GetOneObject(“Select curve for radius dimension”, True, ObjectType.Curve)

if rc != Result.Success:

return rc

curve, curve_parameter = obj_ref.CurveParameter()

if curve == None:

return Result.Failure

```
if curve.IsLinear() or curve.IsPolyline():
print "Curve must be non-linear."
return Result.Nothing
# in this example just deal with planar curves
if not curve.IsPlanar():
print "Curve must be planar."
return Result.Nothing
point_on_curve = curve.PointAt(curve_parameter)
curvature_vector = curve.CurvatureAt(curve_parameter)
len = curvature_vector.Length
if len < RhinoMath.SqrtEpsilon:
print "Curve is almost linear and therefore has no curvature."
return Result.Nothing
center = point_on_curve + (curvature_vector/(len*len))
_, plane = curve.TryGetPlane()
radial_dimension = RadialDimension(center, point_on_curve, plane.XAxis, plane.Normal, 5.0)
doc.Objects.AddRadialDimension(radial_dimension)
doc.Views.Redraw()
return Result.Success
```

if **name**==“**main**”:

RunCommand()

Prompt error, because RadialDimension() does not require parameters!

Hint: “Message: RadialDimension() takes no arguments (5 given)”

Is it wrong? How to correct?

thanks!
