Check this site plan out. you can see the compass showing true north. and the drawing/model is aligned to that. But when I set it to project north, it basically stays the same...how do I get project north to be vertical again? do I really have to rotate the model elements?

I think my intern just drew in Proj North, with the civil underlay alighed to a true north "slant"...:-(

I don't know what you really have but here is a couple of things to understand. 

• Project north is just a drafting convention.  The default when starting is PN is up and all elevations are named accordingly.
• Rotate project north is only on 90 degree increments from that initial setting.  ((Obviously, you can just rename the default elevations to get project north in a different location.) 
• Views oriented to true north means you model may no longer be orthographic in view.  Use the rotate true north to set this value.  In the view you show, the view is set to true north.  If you want to switch to project north then simply switch that setting and if the project was set up correctly, the it will rotate accordingly.
• We don't see any exterior elevation callouts so we don't know if the view was set up correctly.
• Remmber - any view can be rotated.   Simply turn on the crop region, pick rotate and then the crop view boundry and rotate the view.  <<<< THIS IS INDEPENDENT OF TRUE NORTH AND PROJECT NORTH!

Thanks Hub!

yeah. I like the idea of rotating the views themselves, I didnt know to do that. But it looked like I was right, my intern had made proj north and true north the same, lol. had me stumped. Since that happened. and the view was already in PN, I had to rotate all the gemetries to be ortho to the view. then when I went back to TN, I simply had to rotate that back to its angled direction.

It sounds like your intern did not set the views up correctly and now you will have to rotate every view.   YOU DON'T WANT THAT!

To Fix:

1. Set a plan view that shows everyting - full height - to project north.  Your geometry is angled in view - correct?
2. Window all model elements and rotate as appropriate for your planned project north.   You may also have to include exterior elevations.
3. Everything now should be correct for Project North - all of your sheeted views.
4. Now change the view to True north and rotate that in relation to your geometry.
