ID and Properties via Python

benjaminjamesrowley — Mon, 23 Sep 2024 19:15:39 GMT

Hello everyone,

Is there any way to get the information stored in an element's "ID and Properties" field via Python's API?

I tried treating it as any other property and accessing it via either GetBuiltInPropertyId() or GetUserDefinedPropertyId(), but no luck. It doesn't seem to work like "normal" properties.

I found this discussion on the C++ forum, but I can't seem to apply it to Python.

Thanks in advance!

Hi!

It should work with GetBuiltInPropertyID. Where did you get stuck?

Here's a commented example script I adapted from one of my other examples:

############################################################################### # 0. GENERAL SETUP # ############################################################################### from archicad import ACConnection # Connect to a running Archicad instance conn = ACConnection.connect() assert conn, 'Communication Link is not available - timed out' # Definitions for shorter access to API functionality acc = conn.commands act = conn.types acu = conn.utilities ############################################################################### # 1. List of Zone GUIDs # ############################################################################### # Get all zones from the open Archicad Plan zoneElems = acc.GetElementsByType('Zone') # Make a list of Zone GUIDs from the list of zones # (`.elementId` is a very confusing choice of name for the zone's GUID here. # Don't confuse it with the Zones actual Element ID!) zoneGuids = [zone.elementId for zone in zoneElems] ############################################################################### # 2. Element IDs of Zones # ############################################################################### # Get the ID for the built in property representing the Element Id elemIdPropId = acu.GetBuiltInPropertyId('General_ElementID') # Now obtain the actual Element ID of each zone zoneElementIdValues = acc.GetPropertyValuesOfElements(zoneGuids, [elemIdPropId]) ############################################################################### # 3. Ouptut Zone GUIDs and Element IDs of Zones # ############################################################################### # Now we iterate over both the zone GUIDs and Element ID property values which # we obtained in step 2. for zoneGuid, elemProp in zip(zoneGuids, zoneElementIdValues): # The actual property value is a bit nested inside the result of step 2. # (Detail: We can assume that there's only one value and thus use the 1st # element with index 0, since we passed only one Property Id to # `GetPropertyValuesOfElements` in step 2). print(zoneGuid, elemProp.propertyValues[0].propertyValue.value)

Let me know if you have any questions about it!

Best,

Bernd

Hi Bernd,

Thank you for your quick and detailed reply. I have since had a adjust your script to fit mine, and I'm pleased to say it works perfectly.

The problem was that I didn't know the Build In Property Name was General_ElementID. I ran GetAllPropertyNames() and then looked for "ID and Properties".

Thanks again,

Benjamin
