You could select the fixture and use the Swing to Selection camera command to align the view with the base of the fixture and then rotate it along its axis. It will not work if you have lots of fixtures in different orientations though.

No I've also encountered this problem. Swing to selection only lets you rotate a fixtures pan, not the tilt. Then you would need swing to selection section (or something similar)

The command swings to the "nearest" of six possible views. If you first place the view roughly at the correct location and then activate it you can get the section view you're looking for!

Sorry, gentlemen, I'm once again requesting that a fixture be rotated along its main axis.

Try using the Ctrl+4 solution on these fixtures highlighted in orange...
