You can use an edge of the model to orient the view.
		To align a drawing view to a model edge:
 
- Select a linear model edge in a drawing view.
- Click  or Vertical Edge.
The view rotates until the selected edge is oriented horizontally or vertically.
 |  |  | Original view |  |  |  |  | Aligned by horizontal edge | Aligned by vertical edge |  
 
If any views are projected from a view that you rotate this way, the projected views update to maintain their projection.
