How do you create a motion path

I am animating a car that is following a path created in 3d studio max. What I want to do is bring the animation of the car and the path into panda and control the velocity as well as how many cars are on one path.

I tried importing the car’s path separately, and attatching a nodemodel to the path. But the panda doesn’t recognize the spline as a path.

My question is, how do you make a path. if you don’t have maya? Where in the manual do they explain that?

Or is there another way to export a spline from 3d studio, or autocad to make it motion path?

Any help would be appreciated.
