How do I put objects down on a track? I've seen them in cruises and on videos where people put ramps and stuff down. Could you tell me how to do it please?

press shift+u and then activate place objects.

Thank you!

I always like to help people.

But anyway, in your LFS folder there is a folder docs.
Take a look through the files in there, and I think you're gonna be much wiser.
