Grid on non-planar facade

Hello all,
I’m trying to simulate irradiance on a non-planar façade and I need to create an uniform grid on it. I’ve used “create test points” but this component creates a non-uniform grid as you can see on P1. How can I create a uniform grid (rectangular grid) like p2? I would really thankful if somebody can help.
Thanks in advance (598.4 KB)
