Problem with discontinuity for differential growth curve

Hey all!

I’m trying to create a closed differential growth curve using the kangaroo plug in on a 3D surface. Iwant to eventually patch the created polyline and extrude it outwards but right now it’s not allowing me to do so since the bouncysolver is creating an open curve. I’ve assigned the curve as a closed curve so I am confused on why this is occurring.

You didn’t internalize your geometry (curves and surface).

Is there an advantage to Pufferfish rebuild curve over standard GH?
