The preferred practice is to align an auxiliary view with its principal view when possible, which generally makes it easier to read the print. However, there is an option to rotate an auxiliary view when the normal auxiliary view placement takes up too much space on the sheet. When this is done, a viewing-plane line is used to indicate from where the view is taken, and the auxiliary view is placed in any desired location on the sheet. The auxiliary view is rotated as needed and the angle and direction of rotation is specified under the view title.
