If the auxiliary plane is perpendicular to VP and inclined to HP, the view of the object projected on the auxiliary plane is called auxiliary top view and the auxiliary plane is called auxiliary inclined plane and denoted as AIP.

How do you draw an auxiliary view?

To sketch an auxiliary view, you begin with orthographic. views of the object and add projection lines perpendicular (90^◦) to the slanted surface, adding a reference line any convenient distance from the view with the slanted surface.

How are auxiliary views named?

Auxiliary views are named after the name of the plane with which the inclined surface of the object is perpendicular.
