ObliqueProjectionsIntroductionAn oblique projection is one of two major classifications of parallelprojection.ObliqueprojectionsAn oblique projection is the projection of an object in which the projectorsare other than perpendicular to the plane of projection. An obliqueprojection shows front and top surfaces that include the three dimensions ofheight, width, and depth. The front or principal surface of an object (thesurface toward the plane of projection) is parallel to the plane of projection.Surfaces oblique to the plane of projection are not shown in their true size.Oblique projections are superior to orthographic projections in pictoriallyrepresenting objects.Figure 6-2 illustrates the angle of the projectors in oblique projection.Figure 6-2.—Oblique projection.Continued on next page6-4
