How do Points Work?

[2sound]

I don't understand how points work. I understand that they can eliminate collision and friction for car parts hitting the ground, but how to utilize them is unclear.

Do you have to blanket the parts you want to not have ground collision, or are points like on a line, so two points decribe a line of no collision?

Two points decribe a line of no collision is correct. Use points on both ends of the same piece and that piece will either be frictionless or pass through the ground. Does not work on wheels or driver. Use frictionless pieces on sleds or snowmobile. Use collisionless pieces on the underside of pretty much any car to get better suspension action.
