I believe Bud is right. Use the "X" or "Y" rotation to do 360 rotations or beyond .. The sliders appear if you click the down arrow to the right once you highlight the "XY or Z" rotation...but I think you are correct in that you cannot "drag" a 360 rotation in the 3D windows. I couldn't either.

I did read a mathematical explaination of this somewhere in an After Effects forum. If you rotate something 270deg it's the same as rotating it -90deg unless you actually want the keyframes interpreted such that it goes from 0 to 270 over time, then the position at the keyframes is correct but not the tweening.
It gets way more messy in a 3D space. Some of the rotation tools in Vegas work one way and others the other. I don't recall which is which so try using a different method. I think the event pan/crop exhibits this issue but the track 3D tool works the way you'd expect.

I get -360 to 360 in "orientation" & -1800 to 1800 in "rotation". I normally type stuff in.

If you read that in an AE forum & that's how they use it they have something really messed up in the software (maybe that's in another few years. They just figured out the NTSC framerate after all. :D ). -90 isn't anywhere near 270. That's a counter clockwise turn, the others is a clockwise turn. Everything in Vegas does it the proper way: negative degrees go the opposite way of positive degrees.

Some 3d apps don't use the same kind of math formulas & deal with everything in quadrants, so you're limited to -180 to 180. You then need to tell the app to continue the formula if you don't want things to spin backwards. I made a function once that dealt just in quadrants in 3d space. It worked great until things got flat on the x axis. :)

" -90 isn't anywhere near 270"

I've had Vegas, AE and full 3D applications get confused in the same fashion. From a positional view 270 = -90 i.e. 360-90 = 270. Clearly from a rotational view the two are different.
I'm certain there's an explaination about this somewhere on the web but the only references I can find contain way more maths than I think most of us would like to read through.

If I would have went off on a tangent like you guys, I would've been tar and feathered by now. :)

Orientation and rotation are different don’t use orientation to rotate but only to orientate

Orientation will only go up to 360 rotation will go beyond that, Orientation can only go up to 360 because when you get to 361 you are back where you started plus 1 degree so you are facing 1 degree this way or that

for example I can create a 2nd key rotate a plane y 360 and set my orientation to y -360 and it won’t work as you will be in the same position, the y 360 rotation will override the 360 orientation

so create a 2nd key 720 rotation just before that create a orientation key y -360 orientation and what will happen is the orientation will be reversing while the
rotation will be progressing the change will be noticed in speed and pace.

Or create a 2nd key rotation y 720 and and on the same key set the orientation to x 50 and you will get the point.

To get something rotating with an orientation of the same value you will have to put the 3d track in a 3d container

I have done sample and replaced the rotating text with a layout of the project at the end this should help you get a better picture




So 3d text rotating in a rotating 3d box with an orientation
The value of this is you can offset the pivot point of each and create some interesting animation of media

Rory, great example. I am trying to get my head around it but now my head hurts! Can you post the veg?
