Oblique projection is defined as a pictorial projection in which projectors are parallel to each other and inclined to the plane of projection at any angle other than right angle. Orthographic and oblique projections. In orthographic projections (both multiview and axonometric) the projectors are parallel to each other and perpendicular to the plane of projection.
Oblique Projections Oblique Sketches Show exact size and shape of one face of an object Object face with most detail parallel to view plane Relatively easy to draw Oblique Axes Oblique Sketch Oblique Projection Geometry object One face of object parallel to projection plane Parallel projectors make an oblique angle with projection plane image Oblique Projection Angle ( Angle of intersection of projector with projection plane Determines type of oblique projection (Cavalier, Cabinet, General) Classes of Oblique Projections Type of Oblique Receding Axis Scale Cavalier Oblique Projection Angle ( ) 45 Cabinet 63.43 1/2 General 45
