ISOMETRIC PROJECTIONS Lecture 6 Isometric View or Projection • The view or projection obtained on a plane when the object is so placed that all the three axes make equal angle with the plane of projection is called an isometric view or projection. What is ISOMETRIC? • “Iso” means „equal‟ and “metric projection” means „a projection to a reduced measure‟. An isometric projection is one type of pictorial projection in which the three dimensions of a solid are not only shown in one view, but also their dimension can be scaled from this drawing. The three lines AB, AD and AE are meeting at A. These edges are mutually perpendicular to each other in the solid. Since all these edges are equally inclined to H.P, they are making and angle of 120° with each other in the plane of projection; also they are equally foreshortened. This leads us to the problem of selecting an isometric scale.
