I=92ll try to put this as simply as = possible.

In a 3D program I have four points (nulls) that are moving = independently, and then a camera move that rotates around the scene.

I have no problem getting the nulls and the camera move into AE.

However, what I need to do is have a line in AE connect these dots. = Ultimately, I want to animate dashes along this line.

Really, the fact that this is coming from a 3D program doesn=92t matter. = Just imagine four nulls in AE, each moving a bit in 3D space, and then a = camera move as well. How can I get a line to connect those four = nulls?

Thanks in advance!
