
Auxiliary views show the true shape
True Shape is needed for dimensioning
Does not always create an additional view on
a drawing
Can be used to replace one of the principal
views

Inclined Planes




Appears as an edge in a principal view
True shape may be shown by projecting a
view perpendicular to it
Accomplished by drawing a primary auxiliary
view
Often drawn as partial views-exposing only
true shape of inclined plane
