Third-angle projection is most commonly used in America, [6] Japan (in JIS B 0001：2010); [7] and is preferred in Australia, as laid down in AS 1100.101—1992 6.3.3. [8] In the UK, BS8888 9.7.2.1 allows for three different conventions for arranging views: Labelled Views, Third Angle Projection, and First Angle Projection.
