I think you need to define your question a little more, please 
If I read your question right, in 3D modeling, you want the view to "snap" to an orthographic orientation that you have almost achieved with dynamic rotation of the view. If this is the case, you can mapkey your -Orientation- IU and pick a pair of planes or faces to quickly orient your part. This would give you the fastest way to snap to your desired orientation.
I like the idea, however. That would be a unique enhancement if PTC is listen to new ideas. I haven't seen this in any other platform that I have experience with.
