i was remaking the AE intro video made by Andrew Kramer( even if selecting 3D option for a layer it was not switching 3D in output video.

Particles are 3D in nature. You don't have to Enable the 3D switch for particle layer.

If you go to Producer attribute in Effects panel, you will notice that their are parameters for X, Y and Z radius. This means particle effect is interacting in 3d Space.

What u r talking is right. But what do u think after seeing my comp images?
Have a look at my images.
U can see that the 3D tab being selected for logo layer, still its nt aligning in 3D with particl layer.
I wil be shortly uploading 2 videos for demo.

In the image where you get the AE warning, turn off 3D for the layer. Particle emitters like CC Particle World and Particular, use AE's 3D space, can interact with cameras, but they are not true 3D effects. Just for an example enable 3d on a CC Particle layer, twirl open your rotation and rotate the X axis. It becomes flat, because it's not really 3D.

It's that limitation why your second picture the logo and particles are not interacting correctly. You can use the camera to get the particles to rotate with the logo. But based on the layer stack, the particles will always be on top of the logo.

If you use trapcode particular, you can set the logo layer as an obscuration layer and particular will look at it's position in Z space and block out the particles behind it. It also has other methods for turning off particles based on position in Z-space.
