Much like images, a SWF itself is treated like a "video". If you rotate the SWF all the contents rotate in a flat manner.
There's a great deal of collaboration between apps but you have to be reasonable. There's entire frameworks designed for one runtime while the other uses a completely seperate internal version. They don't play nice.
The answer is - you CAN do this - provided you export the Flash files as a PNG sequence of stills - and import that sequence into flash as a movie. = Import > multiple files > png sequence... etc...
Hi Suhas, I had read that help doc... which only says why it won't work. I was looking for a way to make it work.
Ah, your original question made me think you expected objects in flash transformed in 3d to actually transform in 3d the way they do in AE.
You can also export to a movie format if that PNG sequence is too long (keeping audio intact), if that helps.
