Is it my imagination, or does the "Normal To" command work differently in 2005? I thought that if I select NT more than once, it would flip the view direction for the plane being viewed? So the first selection of NT would view the the plane from the top (for example) and then selecting it again, would view the same plane from the bottom. I am pretty sure this is how it worked in 2004, or even 2005 beta. but I do not have those installed anymore to check. Or have I accidentally changed a setting somewhere that affects this.
I thought I had one of my spaceball buttons mapped to this, and it was very useful to quickly switch between view directions, also for sketching.
Thanks to anyone who can remind me of the trick if I have forgotten it!
Cheers, Daniel
