I have a problem with automatic assigment of ID's using ID manager.
In short, I have multiple windows named by width/height but I want Archicad do automatically assign another letters if one of them has specified fire rating class or other classes like thermal resistance.
My example is below.
For now it only works if I specify fireratings on all windows. If they are left blank, ID Manager completely makes all wrong (as seen on example). Is it possible for ID Manager to assign blank firerated windows with same dimensions with the same letter and make another ID when firerating is specified?
