Document Summary

Pictorial assembly drawings you see how the pieces go together (blown apart view). Projectors intersect at finite points, called vanishing points (vp) The representation on projection plane may be considered the view thast would be seen by a single eye at a known point in space (station point). The picture is formed on the projection plane by the intersection of the projecting lines from the object to the focal point of the eye. Projecting plane is parallel to two principal axes. Receding lines along one of the principal axis converge to a vanishing point ( the last supper painting) The projection plane intersects with exactly 2 principal axes, the visual rays converge to two vanishing points. Front of object is parallel to the viewer, face is true size. Projection lines do not converge to a vanishing point. No perspective makes it easier to compare sizes.
