Hi Finema - sorry I did not explain it clearly enough. The script you posted for C4D uses interfaces that exist in C4D for accessing vertices. Currently MoI's own script interface does not have anything set up in it for getting and changing the control points for a curve. So currently it is not possible to make a MoI version of that script. In the future I do want to add more things in MoI to be controllable by script including control points.

Second figure is always symetric and circular or can be any form ?

Am I missing something here.
Why can't you just create a circle, using the object on the right to snap to?

my screenshot are just an simple example..
my goal is to keep the same number of points and their placement on the curve
