Hi Andres, you could shift the list of points and recreate the curve

Thanks a lot Peter, I think that will work fine!

Weird, I could have sworn I wrote a Curve Seam component at some point.

I'll add it for the next release. Until then, you'll need to script this. Create a new VB component, rename the first input "crv" and second input "t". Set the type hint for the "crv" input to "Curve" and the type-hint for "t" to Double. Then add the following code:

 

crv.ChangeClosedCurveSeam(t)   

A = crv

David, I have not idea how you keep track of ALL these Parameters and Components... 

 

I am fine for now with the  help from Peter... I can wait for the REAL component... 

 

Thanks...
