hello:) i have a struggle with my python code. as you can see on the picture i tried to replace the functions of the pink surrounded Component ‘Surfaces’ with a python3 component and a code i wrote. now i have the problem that my code is not incorrect but it does not change anything of my surface i modelled in rhino so it looks empty there and no picture is generated. i think the problem is that out of the untrimmed surfaces (see panel) it gets to only (lists). i dont know how to change - can someone please explain ? and help me with my code! THX

if hasattr(AX, "PointAtStart") and hasattr(AX, "PointAtEnd"):
start = AX.PointAtStart
end = AX.PointAtEnd
axis_vector = end - start

result = []

if geom is None:

if isinstance(geom, rg.Curve):
geo = geom

elif isinstance(geom, rg.Point3d):
geo = geom
else:
# Falls GH Brep direkt
try:
geo = rg.Brep.TryConvertBrep(geom)[0]
except:
geo = None
if geo is None:
continue
# --- Für jeden Winkel kopieren und rotieren ---
for angle in A:
rad = math.radians(angle)
xform = rg.Transform.Rotation(rad, axis_vector, start)
dup = geo.Duplicate()
if dup is not None:
dup.Transform(xform)
result.append(dup)
T = result
