Autodesk Maya weird face normal values


#1

Hello.
i am trying to gather face normal values from objects with this command
string $normals[] = polyInfo -fn $ObjName;
All objects are basic objects so there shouldn’t be any random values like i see here.
this:
FACE_NORMAL 10: 0.000000 -0.074467 0.000000
FACE_NORMAL 11: 0.000000 -0.144696 0.000000
FACE_NORMAL 12: 0.000000 -0.023574 0.000000 : if faces are vertical it should be 0 else 1 or -1 right?
FACE_NORMAL 13: -0.076395 0.000000 0.000000
FACE_NORMAL 14: 0.000000 0.000000 -0.073753
FACE_NORMAL 15: 0.038197 0.000000 0.000000
FACE_NORMAL 16: 0.000000 0.000000 0.036876
FACE_NORMAL 17: 0.000000 0.000000 -0.058191

should be like this(ish):
FACE_NORMAL 55: 0.000000 -1.000000 0.000000
FACE_NORMAL 56: 0.000000 1.000000 0.000000
FACE_NORMAL 57: 0.000000 1.000000 0.000000
FACE_NORMAL 58: 0.000000 1.000000 0.000000
FACE_NORMAL 59: 0.000000 1.000000 0.000000
FACE_NORMAL 60: 0.000000 1.000000 0.000000

Since there are only vertical and horizontal faces Y values should be 0 1 or -1 (as far as i know)
Does anyone now what might be the problem here?
A solution is welcome.

Is there any transformation applied to the geometry? Maybe some scaling?
