How can i get any information about reflines(from family instances)

Revit
3 
OUT = []

def val(x):
    UnwrapElement(x).get_Parameter(BuiltInParameter.SKETCH_PLANE_PARAM).AsInteger()

for p in IN[0]:
    OUT.append(val(p))

i know thats a pit off… i can t “call” a parameter from a refplane(?)

my next “solution” is to get the vector and his informations from the refplane

There is a near topic…

Even when i have that, do i rotate my familyinstance?
