Orthographic Projection Auxiliary Views

Auxiliary View § To accurately view the true dimensions of an inclined surface, one must create a view at 90 degrees from that inclined face. This is referred to as an Auxiliary View. This allows us to view the surface in its true size and shape.

Primary Auxiliary View In order to see a feature in it’s true size and shape, To obtain view the auxiliary must be drawn Many athis feature a part cannot we times must look at it on straight on or perpendicular from the view that allows the linethis of sight.

When to in thetrue plane which the feature exists. to the desired isthat the case weview use (the an auxiliary view. in perpendicular this auxiliary view)feature. the slotted hole is true size and shape.

Secondary Auxiliary View Sometimes you may have a feature that is oblique in all three views. This type of We now can view a true length linefeature needs two auxiliaries to obtain and project with a line of sight perpendicular a perpendicular line of sight on that to the face we would like to see in true surface. size and shape. Line of sight. In the first auxiliary we will try to obtain a view that is looking at the end of one line. Once this auxiliary is projected we then have a true length line Line of sight.
