Document Summary

Engineering graphics has evolved into six major areas: Engineers convey information in three main ways: Also called pictorial drawings, technical illustrations are used to describe products in catalogues, user, and maintenance manuals. Three common types: perspective, oblique, isometric (axonometric) The projection plane is parallel to two principal axes. Receding lines along one of the principal axis converge to a vanishing point. If the projection plane is parallel to one of the principal axes or if the projection plane intersects exactly two principal axes, a two-point perspective projection occurs. If the projection plane is not parallel to any principal axis, a three-point projection occurs with the visual rays converging to three vanishing points. Front face of object is parallel to the viewer, therefore that face is true size. Used to give an indication of depth. Parallel lines remain parallel instead of converging to a vanishing point.
