In Australia the door and window hinge symbol (a triangle) is the reverse of the US. In other words, in Australia, the intersection of the triangle shows the door opening side and the other side represents the hinges, In the US, that is the opposite. That means that all my cabinetry, doors and windows in elevation view, show the hinges on the opposite side to what is normal for Australia and therefore confuses tradesman and builders. Can this symbol, be changed?
