changing this standard view will change the orientation of any standard orthogonal, named and child views in drawings of this model
your changing your standard view to a non standard view. not to much of a big deal if your not rendering your part/assembly very useful if you are. but nothing to freak out over
Every time I change the orientation of a parent view. It is just double checking that you really intend to do this, because any child views will change to match the view you selected. Also, you will lose dimensions that have been placed on those child views.
Is this not what you expected?
edit: I read that a little too quickly. By changing a standard view, you are telling SW that your part isn't oriented in a standard way, and so you are changing its viewpoint. This will affect all of the standard views, which will affect your drawing.
