I have 10000 data sets of (x,y) for which i need to fit a curve. Once I could fit a curve, i need to get points on the curve with an uniform interval. Then I would proceed to patch..and then to stl for my ultimate objective. Right now i'm struck with the curve fitting. Kindly help me out.

There are an infinite number of ways to construct a curve through 10000 point pairs. You will not be able to get a meaningful curve fit unless you can put restrictions on the acceptable formula for the curve.

Thanks Walter, really makes sense. I couldn`t figure out on how to apply a restriction for this irregular kinda profile. Any suggestions?
