  1. Orthographic Multiview Projection Multiview Projection

  2. Multiview Projection The method of viewing an object to obtain a multiview projection is illustrated in figure a. Between the observer and the object a transparent plane is located parallel to the front view. The view is obtained by drawing perpendicular lines (projectors) from all points of the edges of the object to the plane of projection (figure b). The piercing points of these projectors form lines on the projection plane (figure c)

  3. Multiview Projection If planes of projection are placed parallel to the principal faces of the object, they form a “glass box” as shown in figure a. Since the glass box has six sides, six views of the object can be obtained. To show the views on a flat sheet of paper it is necessary to unfold the planes so that they will all lie in the same plane. All planes except the rear plane are hinged to the frontal plane (figure b).

  4. Multiview Projection The positions of the six planes after they have been revolved are shown.

  14. Multiview Projection INTERSECTION VERSUS TANGENCY No line should be drawn where a curved surface is tangent to a plane surface. When a curved surface intersects a plane surface a definite edge is formed.

  15. Multiview Projection examples of intersections and tangencies.
