Is there a way to select all Z-Axis planes on a Brep using grasshopper if you have multiple objects?
… what is that?
vertical planes
thank you, those are horizontal planes, how do i select the all vertical ones?
Instead of computing the angle between normals, I think I would calculate the dot product.
The cosine of 90 degrees is 0…
Thank you Mr. Ricardo, this is good
This definition doesn’t work properly. Please see the attachement.

But this one it is working:
this works good too, it selects the horizontal faces, how don you select the vertical faces?
The dot product is the cosine of the angle between the normal and a given vector.
The cosine of 90° is 0. Two parallel vectors have a dot product of 1, opposing vectors -1…
I would strongly advise to use the dot product and not the angle.
