Graphic override for new construction openings

[Tijana]

Hello

I am working on a house renovation project and I would like to have all my new construction openings shown in blue colour on the elevations. I've set up a graphic override rule and it works just fine when a wall is existing and the opening is new. However if the whole wall is new (obviously windows and doors on it are also new) archicad won't apply that graphic override rule. Any ideas how to overcome this issue? Another way of doing it maybe?

Thanks in advance,

I would add a new classification (ex a true/false one, for windows) for this purpose and use the graphic override to "target" them.

Instead of assigning Classifications to elements, I would recommend creating a Property with a "Boolean" Data Type and using that as a criterion in the Graphic Override Rule.
