For some objects, an auxiliary view must be created before a principal view can be drawn, using a technique called reverse construction. Auxiliary views can be used to draw a view in a specified direction. To create a view of an object in a specified direction, find the point view of the line of sight. | Finding an Auxiliary View Finding an Auxiliary View Given: A multiview set of an object with an inclined surface Find: An auxiliary view showing the true size and shape of the inclined surface Step 1 Draw a reference line parallel to the edge view of the inclined surface to be projected Step 2 Draw perpendicular projection lines from the inclined surface Step 3 Draw a second reference line at a “convenient” location between the view being projected from and an adjacent principal view Step 4 Label the vertices of the inclined surface in the adjacent view Transfer the vertex labels to the edge view Step 5 Measure, then transfer the vertex distances from the principal-principal reference line (H-F) in the adjacent view to the principal-auxiliary (F-1) reference line Step 6 Label the vertices in the auxiliary view, then connect the vertices. This view gives the true size and shape of the inclined surface Finding an Auxiliary View Das ist . | Finding an Auxiliary View Finding an Auxiliary View Given: A multiview set of an object with an inclined surface Find: An auxiliary view showing the true size and shape of the inclined surface Step 1 Draw a reference line parallel to the edge view of the inclined surface to be projected Step 2 Draw perpendicular projection lines from the inclined surface Step 3 Draw a second reference line at a “convenient” location between the view being projected from and an adjacent principal view Step 4 Label the vertices of the inclined surface in the adjacent view Transfer the vertex labels to the edge view Step 5 Measure, then transfer the vertex distances from the principal-principal reference line (H-F) in the adjacent view to the principal-auxiliary (F-1) reference line Step 6 Label the vertices in the auxiliary view, then connect the vertices.
