Hi,

first, in the snippet I don't see, what is assigned to self.geometry and self.geometry_2, but I assume, you just assign what comes out of the methods calculate_geometry and calculate_geometry_2 respectively.
If that is the case, then note following

• the calculate_geometry returns a Polyhedron3D object. This is pure geometry. No information about with which colot to draw it, on which layer, no attributes, nothing. Just vertices, edges and faces.
  
• the calculate_geometry_2 returns a ModelElement3D - an actual element, that can be created in a model
  

What you do in create_as_pythonpart is you create a list of model elements and append the elements to it with append_geometry_3d. You should only give a pure geometry to this method. It's because what this method does, is creating a ModelElement3D container around this geometry. When you do it like:

model_ele_list.append_geometry_3d([self.geometry_2])

Here's how I would adapt it:

def calculate_geometry(self) -> AllplanGeometry.Polyhedron3D:
    return AllplanGeometry.Polyhedron3D.CreateCuboid(AllplanGeometry.AxisPlacement3D(),self.length,self.width,self.height)

def calculate_geometry_2(self) -> AllplanGeometry.Polyline3D:
    pluviale_points = [AllplanGeometry.Point3D(0, 0, 0),AllplanGeometry.Point3D(1000, 1000, -1000),AllplanGeometry.Point3D(0, 0, 0)]
    return AllplanGeometry.Polyline3D(pluviale_points)

def create_as_pythonpart(self, build_ele: BuildingElement) -> CreateElementResult:
    """Create the reinforced beam as a PythonPart with handles and attributes
    Returns PythonPart with handles and attributes """
    model_ele_list = ModelEleList()

    # append the polyhedron
    # omitting the common properties will result in current ALLPLAN settings being used
    model_ele_list.append_geometry_3d(self.calculate_geometry())
    
    # append the polyline, setting common properties explicitly
    polyline_common_props = AllplanBaseElements.CommonProperties()
    polyline_common_props.Color = 6
    polyline_common_props.Layer = 1
    polyline_common_props.Visible = True    # this is the default value anyway, not needed
    model_ele_list.append_geometry_3d(self.calculate_geometry_2(), polyline_common_props)
    
    pyp_util = PythonPartUtil()
    pyp_util.add_pythonpart_view_2d3d(model_ele_list)
    ...

Cheers,
Bart
