Have something wrong in the function AddInterpCrvOnSrfUV() -Python

The function AddInterpCrvOnSrfUV() does not work,because the function coerce2dpointlist() in 254 line in curve.py have 2 parameters.The second parameter is redundant.

The normal work

In my Rhino, must delete “True”,it work.Is this problem in chinese vision only?

my coerce2dpointlist() in utility.py has only one parameter.

In my Rhino

what about function AddInterpCrvOnSrfUV() in curve.py?

This is a coerce3dpointlist,don‘t coerce2dpointlist

AddInterpCrvOnSrf() is different from AddInterpCrvOnSrfUV() .

I’m very sorry,I see the wrong
