Rotating the direction of pinch and spread curves

Hi Everyone,

I am trying to make a model similar to the reference image attached, using grasshopper and pufferfish. I’m not able to figure out how to rotate the direction of the curves made using pinch and spread, so that they run vertically along the vase, rather than horizontally.

I have attached all the files and would appreciate any suggestions,
Thank you!

you could insert a Flip Matrix component on your Points, just before they create the Nurbs curve

Awesome, thank you!
