GH Kangaroo stays flat

Hi,
I’m new to Kangaroo, and I’m trying to produce a tensile surface that has a ridge, but the outcome geometry stays flat, could anyone see what has I done wrong please?

Try to add Load or VertexLoads goal with positive Z vector or strength.
And beware, your points for the OnCurvegoal are supposed to be a portion of vertices of your original mesh…

found out that my points weren’t on the vertices of the mesh, Thanks so much!
