I don't fully understand what you are asking but here is an attempted answer.. You can not actually have an 'aquatic' coaster in NoLimits but you can use 3ds to create an illusion of one.

and how I can make 3ds's?

wings? google is your friend ;)

I search in google but I don't find anything

try sketchup pro or any other 3d designing program.
