That is interesting Aaron, your version must be special.
My ArchiCAD does not pick up Reno Status either when using Parameter Transfer with the syringe cursor shape.
So you say that you have an Existing Wall and a To be Demoed Wall, both are visible, Demo Wall shown with override, you ALT-click (or its Mac equivalent) the Demo Wall, CTRL-ALT-click the Existing Wall and that Wall switched to Demo Status, Floor PLan color overridden and all?
