TIA,

Jan,

I'd not think the CL and CD curves can be "calculated" from the airfoil shape
very easily. Those, and other behaviors, are usually derived from wind tunnel
testing.

Having said that, I'd not be too surprised to find someone has written a program
that approximates CL/CD from a database of some kind.

Anyway, question...

Are you trying to plot the airfoil shape from a table of ordinates?
Or are you trying to generate a shape from a mathematical algorythm?
