silly question here.
in rvb, the rhino.curvestartpoint method is used as

rhino.curvestartpoint(arg1,opt arg2,opt arg3)

it seems there is just arg1 in pythonscript. so, if i wanna shift the startpoint to another point, it seems i have to use objectgrip method now.

so can we modify this method as the rvb one?
also the curveendpoint and curvemidpoint methods.
