Get element ids from an attribute

[JuniperScarr]

Is it possible to get the element ids by calling for an attribute such as a Group name? I am generally looking for different ways to get elements ids without them having to be active in a model.

Any help on this would be appreciated!

from collections import defaultdict

import cadwork
import element_controller as ec
import attribute_controller as ac

element_ids = ec.get_all_identifiable_element_ids()

element_dict = defaultdict(list)
for element_id in element_ids:
    element_dict[ac.get_subgroup(element_id)].append(element_id)

Hi @JuniperScarr ,

if it can help, I created this simple function where you pass as arguments an attribute function (for example, ac.get_group) and a list (of attribute values), and it returns a list of ids that match (optionally, you can pass as third argument the list of elements):

def get_ids_by_attribute(attribute_function, target_value, element_list = ec.get_active_identifiable_element_ids()) -> list[int]:
    matching_ids = []
    for elem_id in element_list:
        try:
            if attribute_function(elem_id) in target_value:
                matching_ids.append(elem_id)
        except:
            # In case the attribute is not available or errors out
            continue
    return matching_ids
