Create a plane perpendicular to X

Greeting,

Both project and survey coordinates are given. I would like to create multiple planes that perpendicular to x in survey coordinate shown as below(not in project coordinate).

This is what I get so far. Not sure if the highlighted in green is the right one to use.

Thanks for the help.

Perpendicular to the x-axis? That would just be the normal vector in this case, which would be (1,0,0).

Yes, you are right. Thanks for this. I think it would be (0,1,0).

The normal vector of a plane is the direction perpendicular to it (in this case, a plane is defined by 2 vectors, the normal vector is then the vector perpendicular to both of those vectors, also called the cross-product). So a plane perpendicular to the x-axis would be any plane with a normal vector equal to (or parallel to) the x-axis.

Yes, you are right.
