A perspektive grid for bakgrounds etc

Im workig on my bakgrounds and would like a parespektive grid for reference when putting out props and furnitures etc. also for animating the charakters. i made one of my one own that works but im sure there is a smarter and faster way than mine.
Dear reader How would u do it?

I would take a digital photo of some graph paper (pref. quad graph paper), import it into AS, and then swivel it thru the X axis. I've used this technique for 3/4 view walks with footprints. It's quite easy to do both one- and two-point perspective this way by also swiveling it thru the Y axis if you want...

What a clever idea.

Thanks! You have to be inventive if you are lazy!

Very clever idea. I wonder whether it's simple enough to be added as a function/feature?

Thanks, slowtiger!

I tried out Jahnocli's method and realized that you can throw in some point animation when you pan to simulate 3d. http://vimeo.com/9040137

I just put in a key frame for the first camera position and the last. On the same frames I put in keys for the box according to the grid.

Of course, it's easier on a really basic shape like this. But the ability to position the vector drawing along the z axis cuts down on moving points around because you only have to edit points that are not on their correct plane. I hope that makes sense.

That's something I wanted to indicate with my file. All lines have one starting point in the middle. If you select all these middle points at once you can move them easily together. Now do this with some perspectively constructed item ...

Oh, sorry about that. It should be working now.

I put up a second test of the grid combined with slowtiger's center of vision approach. I put the perspective lines on a layer immune to camera movements and used that as a reference for creating the angles. http://vimeo.com/9063126

The two approaches work really well together. The grid helps with position and scale and the center of vision point helps to get the angles more precise. And you don't even need to bother with diagonal vanishing points. Yay!
