How to set element classifications by the layer with Python add-on

Hi,

I'm trying to create a script that would set same classification value to all elements in specified layer regardless of the element type. At this point I have got the script working but not quite as I hoped. Instead of giving classifications only to the elements in specified layers, script gives same classification value for every element in the project. I might have a guess why it does that, but I have not found a fix for it.

Any solutions for how to get the script working right?

Here's the code:

from Archicad import ACConnection import Archicad import sys import re from Archicad.releases.ac25.b3000types import ElementId, ElementPropertyValue conn = ACConnection.connect() assert conn conn = ACConnection.connect() acc = conn.commands act = conn.types acu = conn.utilities elementIdBuiltInPropertyUserIds = acc.GetAllElements() Layer = acu.GetBuiltInPropertyId('ModelView_LayerName') elemenType=acu.GetBuiltInPropertyId('General_Type') value =acc.GetPropertyValuesOfElements(elementIdBuiltInPropertyUserIds,[Layer]) value2=acc.GetPropertyValuesOfElements(elementIdBuiltInPropertyUserIds,[elemenType]) class1 = acu.FindClassificationSystem('AC_Classification') class2 = acu.FindClassificationItemInSystem('AC_Classification','Building Element Proxy') class_id = act.ClassificationId(class1,class2.classificationItemId) NumberArray = [] for index,element in enumerate(elementIdBuiltInPropertyUserIds): element = element.elementId Info1 = value[index].propertyValues[0].propertyValue.value Info2 = value2[index].propertyValues[0].propertyValue.value print("Layer name: ",Info1,"----Element type in layer:", Info2) if "Structural - Bearing" in str(value): elem_classes = [] for element2 in elementIdBuiltInPropertyUserIds: elem_class = act.ElementClassification(element2.elementId,class_id) elem_classes.append(elem_class) acc.SetClassificationsOfElements(elem_classes) print(elem_class)

And after running the script, here's the outcome:

Layer name: Structural - Bearing ----Element type in layer: Wall Layer name: Structural - Bearing ----Element type in layer: Column Layer name: Structural - Bearing ----Element type in layer: Column Layer name: Structural - Bearing ----Element type in layer: Column Layer name: Model Unit - Zone ----Element type in layer: Zone Layer name: Model Unit - Zone ----Element type in layer: Zone ElementClassification {'elementId': {'guid': 'DE8A1990-E082-4276-BE02-834D0EBF010D'}, 'classificationId': {'classificationSystemId': {'guid': '632C30E5-2B82-4A75-BFAD-D52FEBCE9A4A'}, 'classificationItemId': {'guid': '7272DAE2-F291-4062-A660-574C7E56DC66'}}} ElementClassification {'elementId': {'guid': 'ED65B0A9-DD68-4086-9E93-09D426134059'}, 'classificationId': {'classificationSystemId': {'guid': '632C30E5-2B82-4A75-BFAD-D52FEBCE9A4A'}, 'classificationItemId': {'guid': '7272DAE2-F291-4062-A660-574C7E56DC66'}}} ElementClassification {'elementId': {'guid': 'C9A4FC19-4000-4490-B0B7-A29D39AD7EA8'}, 'classificationId': {'classificationSystemId': {'guid': '632C30E5-2B82-4A75-BFAD-D52FEBCE9A4A'}, 'classificationItemId': {'guid': '7272DAE2-F291-4062-A660-574C7E56DC66'}}} ElementClassification {'elementId': {'guid': 'FA45CD41-0799-4269-91E2-F3BE5839909B'}, 'classificationId': {'classificationSystemId': {'guid': '632C30E5-2B82-4A75-BFAD-D52FEBCE9A4A'}, 'classificationItemId': {'guid': '7272DAE2-F291-4062-A660-574C7E56DC66'}}} ElementClassification {'elementId': {'guid': '82619F49-B5C5-454F-9DEC-D613F8EEEDE3'}, 'classificationId': {'classificationSystemId': {'guid': '632C30E5-2B82-4A75-BFAD-D52FEBCE9A4A'}, 'classificationItemId': {'guid': '7272DAE2-F291-4062-A660-574C7E56DC66'}}} ElementClassification {'elementId': {'guid': 'D11CC0E9-21C7-43C9-B3E5-03EFE696DD66'}, 'classificationId': {'classificationSystemId': {'guid': '632C30E5-2B82-4A75-BFAD-D52FEBCE9A4A'}, 'classificationItemId': {'guid': '7272DAE2-F291-4062-A660-574C7E56DC66'}}}

As you can see that the script gives classification "building element proxy" for every element instead giving it only for the elements in the "Structural - Bearing" layer.

Try replacing the last "if" with

elem_classes = [] for index,element2 in enumerate(elementIdBuiltInPropertyUserIds): if "Structural - Bearing" == value[index].propertyValues[0].propertyValue.value: elem_class = act.ElementClassification(element2.elementId,class_id) elem_classes.append(elem_class) acc.SetClassificationsOfElements(elem_classes) print(elem_classes)

Thank you very much Gerry! Your solution made the script do exactly what it was meant to do!
