  7. First angle projection is like keeping a solid in front of a screen and seeing it from the other side of the screen. It is just projecting all the edges, points features etc.. over a plane that is behind the solid. answers.yahoo.com In first-angle projection, the projectors originate as if radiated from a viewer's eyeballs and shoot through the 3D object to project a 2D image onto the plane behind it. In third-angle projection, the projectors originate as if radiated from the 3D object itself and shoot away from the 3D object to project a 2D image onto the plane in front of it. http://en.wikipedia.org/wiki/Engineering_drawing

  8. Important assumption: View the object from the right! In first-angle projection, the object is conceptually located in quadrant I, i.e. it floats above and before the viewing planes, the planes are opaque, and each view is pushed through the object onto the plane furthest from it. http://en.wikipedia.org/wiki/Multiview_orthographic_projection

  9. Important assumption: View the object from the right! In third-angle projection, the object is conceptually located in quadrant III, i.e. it is positioned below and behind the viewing planes, the planes are transparent, and each view is pulled onto the plane closest to it. http://en.wikipedia.org/wiki/Multiview_orthographic_projection
