How do I enter a specific view rotation?

Currently, I have:

System Options > View > View Rotation, Arrow keys

set to 15 deg.

Say I want to tilt a view back about the X axis by 7.5 degrees but do not want to change the above setting. How would I “dial in” that exact 7.5 degrees?

For clarity, I am talking about a view, not mating.

Thanks.

If you ALT Drag the middle mouse button
you can ROLL the view but I do not know how to roll it a set amount of degrees

to roll a set amount of degree i think you will need to rely on api

(this is actually on my bucket list for some time now)
basically my 2cents is the macro will change your view rotate increment based on your input, then rotate the view using the increment, then revert the increment

In case you need it, i had created a macro that rotate the view based on specific angle at here:

Create a plane at that angle, then select the plane and set your view normal to.

and then they can make a new view and jump back to it anytime they like

Are you talking about a drawing view? If so just insert a regular view and then use the rotate command

If your talking a model view use the normal to (either clik on a part face or make a plane like Dan said)
