Selecting specific series of points from data tree

[user517]

"Hi everyone,

I am struggling to select only the right-sided series of points from a mesh. Can anyone help me with this? Also, what strategy would you suggest as an efficient approach?"

Here are two options:

1. extract the x coordinates and filter the points whose x coordinate is not 0.
2. calculate the dot product between the face normals and the x vector. If this is 1, the face points towards positive x
