Auxiliary Views. An auxiliary view is an orthographic projection of an angled surface on an object, which appears foreshortened in a typical multiview drawing.Auxiliary views are used to show the true size and shape of an angled surface and its features.. Auxiliary Views. Foreshortened surfaces on multiview drawings do not give a clear or accurate representation of size or shape and should not be dimensioned..
