About This File
This nice script summarize all Space-Areas, which are part of the same Appartement Number and shows the result in a symbol based stamp. Alternatively you can get apartment. Alternatively we can pull out sum of apartment area with a worksheet. But this Marionette is also a nice method to do this.
1. The Marionette Objects access to the field "11_Room ID" of the space object. Every other field can be used if necessary by editing script
2. with the Marionette PIOs field "Raum ID" you can tell the stamp, which apartment should be displayed.
