Changing Length with Python

Hello everyone,

I've been trying to edit walls with the Archicad Python Wrapper and i had success changing the 'General_Height'and 'General_Thickness' of a wall, but 'General_Length' appears to be a read-only property.

It appears as 'General_Width' is tied to 'General_Thickness' and is not the right parameter.

In my example projects the 'General_3DLength' corresponds to the actual length of the wall, but the property is read-only.

My question is: Is it possible to change the length of a wall or am i limited to Height and Thickness?

My Code (excuse my variable names):

from Archicad import ACConnection conn = ACConnection.connect() assert conn acc = conn.commands act = conn.types acu = conn.utilities singleWall = acc.GetElementsByType("Wall") gHoheId = acu.GetBuiltInPropertyId("General_Height") gBreiteId = acu.GetBuiltInPropertyId("General_Width") g3DLangeId = acu.GetBuiltInPropertyId('General_3DLength') gDickeId = acu.GetBuiltInPropertyId("General_Thickness") wandHoheWert = act.NormalOrUserUndefinedPropertyValue('length', 'normal', 4.0) wandBreiteWert = act.NormalOrUserUndefinedPropertyValue('length', 'normal', 4.0) wand3DLangeWert = act.NormalOrUserUndefinedPropertyValue('length', 'normal', 4.0) wandDickeWert = act.NormalOrUserUndefinedPropertyValue('length', 'normal', 4.0) nH = act.ElementPropertyValue(singleWall[0].elementId, gHoheId, wandHoheWert) nB = act.ElementPropertyValue(singleWall[0].elementId, gBreiteId, wandBreiteWert) n3 = act.ElementPropertyValue(singleWall[0].elementId, g3DLangeId, wand3DLangeWert) nD = act.ElementPropertyValue(singleWall[0].elementId, gDickeId, wandDickeWert) rH = acc.SetPropertyValuesOfElements([nH]) rB = acc.SetPropertyValuesOfElements([nB]) rD = acc.SetPropertyValuesOfElements([nD]) r3 = acc.SetPropertyValuesOfElements([n3]) print(rH) print(rB) print(r3) print(rD) Console Output: [SuccessfulExecutionResult {'success': True}] [FailedExecutionResult {'success': False, 'error': {'code': 6800, 'message': 'Value of property definition is read-only (property definition guid: "3799B10A-61C5-4566-BF9C-EAA9CE49196E")'}}] [FailedExecutionResult {'success': False, 'error': {'code': 6800, 'message': 'Value of property definition is read-only (property definition guid: "BA0E29BD-A795-4A93-A33F-C2C17B46C33A")'}}] [SuccessfulExecutionResult {'success': True}]

I believe that width and length are calculated values and can not be changed. Width refers to the set width of a composite or profile and would not make sense to change it. Length is the length of a wall as defined by its neig points Only the elements that these properties refer to can be changed through their info box(s) or the C++ API.

Thank you. I guess i will start studying C++ or find a work around 😄
