Unformatted text preview: September 25, 2008. Class 5.2 Used to create true size views of surfaces that do not appear true size in any orthographic view. Generally apply to inclined surfaces. True sizes are often necessary for pattern layouts. Are created by transferring distances from a folding line to each orthographic view. Primary auxiliary views are projected directly from an orthographic view. Secondary auxiliary views are projected from a primary auxiliary view. The auxiliary plane is parallel to the inclined surface. The auxiliary plane is perpendicular to the frontal plane and hinged to it. The folding plane is numbered F/1 for the Folding/Auxiliary 1 plane, as an example. F H F 1 Number the corners on the view that appears misshaped. Transfer the numbers to the view that appears as an edge. Transfer the distance to each numbered point from the folding line between orthographic planes from the auxiliary folding line. Connect the dots. Place a TS for true size on the true surface. Be sure to number your auxiliary folding line. Before: Orthographic views with an inclined surface. After: Auxiliary view that shows true size and shape. Sizing a model of a physical object so that the model fits in a given space....
