Help with splines and meshes

[Anonymous]

I have these separate "ramps" (each is indicated in a different color) that each begin and end at ground level and then curve up multiple levels. I assume the easiest way to do this would be with meshes, but when I try to bring them into AC12 (they are generated in Illustrator) it makes thousands of little lines instead of a single smooth spline or curve, so when I make a mesh out of it there are thousands of nodes, making it impossible to get it to smoothly do what i want. I would expect to divide each color ramp into 10 or so sections to generate the ramping portion.

anyone have any ideas on how to best model this?

quick render...Ill post the final project when we get done with it, who knows how much will change by then.

Its going to be a sports arena in a park setting...the ramp going up will possibly be grass and leads to a some sort of park/event space on the top.

this is day one of 5 weeks so there is a long way to go

thanks!
