I know the basics.
What I am specifically looking for is more than just the usual NumPad 3,4, 2 and 8. I want to do it from any angle in my window. With a mouse.
I can rotate my view around an object by holding down the Middle Mouse button, but I want to do it linearly.
Hard to explain. For example, if I use the NumPad to rotate an object by pressing the Number 4, It rotates my view with 7.5-degree increments every time. It is not exactly what I need when matching edges that are far apart.
I want to do it with freely with the mouse without losing the angle of view. Kind of lock my view in place then I rotate around it in micro-increments.
Maybe there is a setting (or add-on) in the Preferences for that , and I never saw it all these years.
