Flip Surface Normal towards a point

Hello All, I have a bunch of vertical surfaces and a point in between all of them. As you see some of the surface normals are pointing outwards and some in the direction of the point.


I’m wondering if there is a way to flip all the surfaces so that all the surface normals point towards the point, as I manually did here:

here’s the file:

You could also use Plane Closest Point.

wow, never thought about it this way!

I think in his example the surface happened to cover the “center point”. but not his original intention.

Thank you all so much this works!!

Improved a little bit the HS_Kim definition and eliminated the need to define a point.
