Allplan Forum: [PythonParts] How do I attach custom attributes to a Wall?

Hello,

I'm generating walls in a PythonPart without problems, with some configurations like a custom layer, a tier of type called "Concreting work" or a plane reference with a height from the bottom. Everything seems to work fine till this point, however, when I try to attach an attribute to the wall, the generated wall in Allplan does not have the attribute, ignoring the configuration done code-behind. I've tried different ways to do so, taking as reference some existing examples, although they are all for 3D Objects since I've found no examples with walls.

Attached to this issue I add the class I use to create a Wall, which is called from the main script as follows:

def create_element(self):
        python_part_util = PythonPartUtil()
        python_part_util.add_architecture_elements([self.create_test_wall(AllplanGeo.Point3D(3600,0,0), 1)])
        pyp_transaction = PythonPartTransaction(self.coord_input.GetActiveViewDocument())
        base_elems = pyp_transaction.execute(
            placement_matrix= AllplanGeo.Matrix3D(),
            view_world_projection= AllplanIFW.ViewWorldProjection(),
            model_ele_list=
                python_part_util.create_pythonpart(
                    self.build_ele_list,
                    type_display_name = "PythonPart Parent with child objects",
                    placement_matrix=self.placement_mat
                ),
            modification_ele_list= ModificationElementList(),
            uuid_parameter_name = "test_uuid"
        )

def create_test_wall(self, input_pnt: AllplanGeo.Point3D, index: int):
        self.wall = Wall_PP(
            self.coord_input.GetInputViewDocument(),
            random.random() * 3600,
            input_pnt,
            1196,
            120,
            2996,
            index,
            True,
            False)

        return self.wall.wall_element()

The fragment of the attribute attachment:

        wall = AllplanArchElements.WallElement(self.wall_prop, self.wall_axis)

        attribute_list = []
        attr_list = []
        attr_list.append(AllplanBaseElements.AttributeString(1083, "3000x1200x120mm"))
        attr_set_list = []
        attr_set_list.append(AllplanBaseElements.AttributeSet(attr_list))
        attributes = AllplanBaseElements.Attributes(attr_set_list)
        wall.Attributes = attributes

Hi,

I am also surprised, but apparently, it is not possible to append custom attributes to a wall (nor wall tier, nor wall as a whole), when creating it.

However, as a workaround, I would suggest you to append them after the wall is created. This is possible in your case, because you are calling PythonPart transaction yourself. Use the ElementsAttributeService to do it, like

        attr_list = BuildingElementAttributeList()
        attr_list.add_attribute(1083, "3000x1200x120mm")
        
        AllplanBaseElements.ElementsAttributeService.ChangeAttributes(
            attr_list.get_attributes_list_as_tuples(),
            wall_adapters)

Where wall_adapters is the BaseElementAdapterList with walls, you want to append the attributes to. These should be WallTiers or Walls (depending on whether you want to add the attribute to the wall as a whole or to individual wall tiers).

After you create the walls with the PythonPartTransaction, you get a list of adapters of all the created objects. In your code snippet, this is base_elems:

base_elems = pyp_transaction.execute(... )

because there will be many objects in this list (axis adapter, adapter to attribute container, adapter to each wall tier), you will have to filter it. You can use filter() functionality of python and the SelectioQuery object, to get only walls, e.g.

wall_filter = AllplanIFW.SelectionQuery(AllplanIFW.QueryTypeID(AllplanElementAdapter.WallTier_TypeUUID))
walls = AllplanElementAdapter.BaseElementAdapterList(list(filter(wall_filter, base_elems)))

Let me know, if that helped

Best,
Bart

Hi bmarciniec,

Thanks for your response.

As you suggested the solution is to apply the attributes after creating the walls with the ElementsAttributeService, however, this only works for AllplanElementAdapter.WallTier_TypeUUID, if you desire to add these attributes to the whole wall (AllplanElementAdapter.Wall_TypeUUID) the initial issue persists and Allplan ignores your changes.

I am also surprised, but apparently, it is not possible to append custom attributes to a wall (nor wall tier, nor wall as a whole), when creating it.

From my point of view, it's a bit anomalous to not be able to create an element with its attributes. Being forced to add attributes after creation can lead to the loss of element tracking, and not knowing which element needs which attribute; luckily it's not my case, but it hinders the modelization.

Also, generating Walls inside PythonPart (as an object) causes other strange malfunctions to Allplan regarding attributes, which are not found when creating a standalone wall from a PythonPart (as a script):

Whole Wall default attribute specification is not generated.
Manually added attributes in Allplan to the whole wall attribute list are deleted/ignored when saving those attributes and are no longer attached when entering the list again.
The attribute list is no longer accessible from right-click contextual menu.

Is it planned to be fixed or implemented in future updates?

Hi Arnau,

Which version of ALLPLAN are you using? I haven't encounter the problem of the attributes being ignored by the ElementsAttributeService when trying to apply them on a AllplanElementAdapter.Wall_TypeUUID.

Regarding the issue with applying the attributes on a wall when creating it - I totally agree with you. We have put it in our backlog which means we already planned to fix it. However, I cannot tell you any timeframe, when it happen. Probably not in ALLPLAN 2026.

Best,
Bart

Hi bmarciniec,

Thanks for your update on this issue.

I am working with Allplan 2025-0-4. As I said, in my case, I cannot even enter attributes manually when a Wall is created from a PythonPart, which may also be causing the problem with setting attributes to an AllplanElementAdapter.Wall_TypeUUID.

Thanks,
Arnau
