Prompt error, because RadialDimension() does not require parameters!
Hint: “Message: RadialDimension() takes no arguments (5 given)”
Is it wrong? How to correct?
The code works fine in Rhino for Mac v.5.5.3, but doesn’t seem to work in RhinoWIP for Mac 6.
I don’t know which version of Rhino, Windows or Mac, beta or golden master, you are using, but the issue seems to be caused by Rhino.

Please take a look at this guide. It shows you how to format code correctly in Markdown. I had to do some otherwise unnecessary clean-up, just to be able to run your code!
As mentioned above, it works fine in Rhino for Mac 5! It draws a little cross and annotates the curve with a radial dimension.
The RhinoCommon reference states that RadialDimension() is supported in Rhino for Mac 5.4
and Rhino for Windows 6.15.
I can only confirm that your script works in Rhino for Mac 5.4, beyond that I don’t know!
You simply might have discovered a bug in Rhino 6 (cf. @Helvetosaur’s comment)?
