HAving re-registered the AutomationInstanceData.dll file I can now read all my datagroup properties for each element in a file. but this is a read only function.
How can I change the value of a datagroup property using VBA ?
e.g I want to change the Wall Finish of a Space to "Plaster".
There does not seem to be a way to write back a value to a datagoup property item ?
I have several thousand spaces that I want to be able to maintain externally via an excel spreadsheet.
Can anyone help ?
Thanks Stephen
