The drawing is CLICK HERE FOR DRAWING AND underneath which clearly shows which angle of projection has been used. with sufficient clarity, a three-dimensional object on a two-dimensional piece of paper The drawing must show quite clearly the detailed outlines of all the faces and these outlines must be fully dimensioned If the object is very simple, this may be … a) Right side view is right side of front view In 1st angle projection the _________ lies between ___________ and ____________ Orthographic Views and Multiview Constructions 4-5 FIRST-ANGLE PROJECTION In first-angle projection, the object is placed in front of the image planes. First angle projection method is used inEurope, India, Canada and the rest of world as a default projection system. The plan view is a view seen directly from above. 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.
