Voronoi on non rectangular surface

I am trying to make a voronoi structure on a non rectangular surface like this one:

Is it possible?

If the base surface is planar, then you can use Region Union afterwards on all the voronoi cells and the boundary. However some cells may appear on both sides of the slits.

I think i did something wrong:

I would like to trim all the lines of the voronoi structure outside the curve

Try Region Intersection (RInt)
A Input are the cells and B Input your boundary curve.


Oops, that’s what I meant, sorry.

Thank you so much :smile:
