The plane which is perpendicular to a horizontal plane and inclined to the vertical plane is called an auxiliary vertical plane. This plane gives auxiliary front view.
The plane which is perpendicular to the vertical plane and inclined to the horizontal plane is called an auxiliary inclined plane. This plane gives auxiliary top view.
The single view usually projected from one among the 6 principal views. If this plane is perpendicular to any principal plane, then a shape on such a drawing is called Primary Auxiliary Views.
The single view usually projected from another primary auxiliary view. If the auxiliary plane isn't perpendicular to any principal plane, then the form shaped on such plane is named Secondary Auxiliary Views.
Auxiliary View that is ready in such a plane that is perpendicular to 1 principal plane and makes the inclined view with the opposite two principal planes is named Primary Auxiliary read.
There are three sorts of Primary Auxiliary Views because of three principal planes as follows:
This type of projection allows the viewer to see only the part of that drawing that needs to be illustrated in its true undistorted surface.
A partial auxiliary view saves precious time and produces a drawing that is much more readable. The full auxiliary view is strenuous to draw, read, and visualize.
