AUXILIARY SECTION.— An auxiliary view maybe a sectional, rather than a surface, view. In the upper left part of figure
In some cases the shape of an object will be such that neither the normal orthographic view nor the auxiliary
Sometimes the total auxiliary view is not needed. Such a view could possibly even make the drawing confusing. In this
The first step in the drawing of any auxiliary view is to draw the object in normal multi-view projection, as
In theory, there are only three regular planes of projection: the vertical, the horizonal, and the profile. Actually, it is
A circle on a surface that is parallel to the plane of projection will project as a circle. A circle
In a multi-view orthographic projection, a NORMAL line is one that is parallel to two of the planes of projection
It is often the case that a two-view projection is all that is required. The view at the top of
