First-angle projection was widely used in the UK, but during World War II, British drawings sent to be manufactured in the USA, such as of the Rolls-Royce Merlin, had to be drawn in third-angle projection before they could be produced, e.g., as the Packard V-1650 Merlin. i.e. Die drei Projektionen werden nun in einer Ebene gezeichnet, indem man die räumliche Anordnung der drei Ebenen längs der x-Achse aufschneidet und in die yz-Ebene umklappt. In this projection technique, Placing the object in the third quadrant puts the projection planes between the viewer and the object and is shown in figure, Difference between first- and third-angle projections. Diese „Bauzeichnungen“ dienen den Planern dazu, die Dimensionen eines Bauwerkes genau zu definieren. Projizierende Ebenen werden in der entsprechenden Bildebene als Gerade abgebildet. PARTS OF A FIRST ANGLE PROJECTION 7. Either first angle projection or  third angle projection are used for engineering drawing.  Second angle projection and fourth angle projections are not used since the drawing becomes complicated. The difference between first angle and third angle projection is the way that a 3D object is rotated on a drawing to show the different sides and views. In the first angle projection system, the protest put in the principal quadrant and in third angle projection system the question put in the third quadrant. First Angle Projection is one of the ways of representing three-dimensional objects with respect to two dimensions which is commonly used in Europe and most of the world except the United States. Bei der Anordnung der Ansichten auf dem Papier gibt es zwei Systeme: Die nebenstehende Symbolik ermöglicht anhand eines abgeschnittenen Kegels und dem Trapez als Vorderansicht die Kennzeichnung der gewählten Methode.
