View rotation is now possible to do by angle or by horizontal/vertical edge. Unfortunately it have to be strictly the edge geometry from the model.
I can imagine how small probability is that your have not any straight lines in the View. Unfortunately in my case it is quite often because the most of the shapes are based on cones and it's section. Sometimes it is quite challenging to rotate the veiw into requested orientation.
Even if you have the straight line in the View, it doesn't have to be H/V oriented exactly as needed for proper rotation and need be calculated the angle.
I would be happy to have an oportunity to rotate the Views by Base Planes os Work Features, or maybe even Sketch Lines. Probably it should not be so complicated change, mainly because the view orientation is not permanetly linked to selected edge orientation (When edge changed, the View orientation is not updated).
Thanks
