View Rotation

[v5newto]

I was wondering if anyone can tell me if there is a way to rotate your view on the screen, using spaceball (rotate command icon or 2 mouse button method), about a LINE, instead of a focal point. For example, if you had the face of a clock you can set center point as focal point and then move cursor around outer screen, outside of red ball, to spin face of clock in a circle. The question is, if you had a line from 3 to 9 on the clock, is there a way to set this line as a rotation axis so you can flip the VIEW of the clock over like a coin from heads to tails? Thank You, in advance for any help anyone can provide.

If you hold SHIFT and use the up/down arrow keys you can rotate the view as you described. Also, if you go into options/general/display/navigation tab (down to the bottom) you can change the display rotation increment.
SHIFT+CTRL allows you to 2D rotate as well.

If you actually want a line to be the axis (even when viewing in ISO), use the compass.
Drag the compass to the line and then toss it back in the corner to get the orientation. Then middle-mouse-button an endpoint on the line. This'll center the screen on the endpoint, and the line. You can then manipulate the compass rotate handle (or I suppose the spaceball) and it should flip about the line.
