yeah i watched entropy's tutorials which helped, but its still confusing.

I got the hang of it though the geometry and physics arent hard at all and its basically ending the coaster im having problems with.

I don't like newton I use maya 3d model it not as confusion like newton but its a long process and I made an X2 reaction in their for my JR engineer class in school it took me a month to make design and making it into a model... But if u make 3d model take your time...

But I might use newton to make custom cars for my no limits coaster.

You can't make custom cars for no limits coasters. Newton is a FVD (force vector design) program, meaning it uses g forces to create the track.

My bad I mean blender
