You create an auxiliary view by projecting from an edge or line in a parent view.
You can place the view only in perpendicular or parallel alignment to the selected edge or line.
To create an auxiliary view from a projection line external to the view geometry, you can use Section View.
The default style of auxiliary view annotations is set in the Style and Standard Editor.
