Auxiliary views are orthographic views used to present true-shape views of slanted surfaces. Figure 4-51 shows an object with a slanted surface that includes a hole drilled perpendicular to the slanted surface. Note how the right-side view shows the hole as an ellipse and that the surface A-B-C-D is foreshortened; that is, it is not shown at its true size. Surface A-B-C-D does appear at its true shape and size in the auxiliary view. The auxiliary view was projected at 90° from the slanted surface so as to generate a true-shape view.
An orthographic view drawn perpendicular to a slanted or oblique surface.
Figure 4-52 shows an object that includes a slanted surface and hole.
Exercise 4-10 Drawing an Auxiliary View
Create a drawing using the ANSI (mm).ipt format. Click the Base View and Projected View tools on the Create panel under the Place Views tab, and create a front and a right-side view as shown in Figure 4-53.
Click the Auxiliary View tool, then the front view.
The Auxiliary View dialog box will appear.
Enter the appropriate settings, then click the slanted edge line in the front view.
In this example, a scale of 1:1 was used.
Move the cursor away from the front view and select a location for the auxiliary view.
Click the left mouse button and create the auxiliary view.
