An Auxiliary View is similar to a Projected View, but it is unfolded normal to a reference edge in an existing view.
You can create an auxiliary view of an exploded assembly view.
You can use sketched lines for folding. In this example, to properly orient the auxiliary view, add a perpendicular relation between the sketched line and the temporary hole axis.
Example: Using an Auxiliary View
The angled edge on the front view is selected for the Auxiliary View, which is at the upper right, with a view arrow labeled C.
