Voronoi doesn't use my curve as-is, interpolates certain control points

I’m trying to use a curve as a voronoi source, but grasshopper won’t take the curve as-is, it interpolates certain control point positions to make a simple rectangle.

I’ve also tried to use a rectangle, and then use the curve to make a boundary surface, but it cuts off the voronoi cells. (left version uses base curve, right version attempts to use rectangle to build, and curve to crop)

What am I missing?

What is your question?

Hi,

you can have voronoi cells on any arbirary planar surface by first populating a geometry with points (so the points populate the custom surface) then by using the Brep | Brep component to intersect the voronoi with the original surface

Quan Li is inferring that you did not internalize your geometry data in the definition.
