symmetrical airfoil sketching

Hello,
I have, in the past with autocad2000 , sketched Wing Ribs for  a remote control Biplane ( to the best ofmy sketching skills at the time), using arcs.

Question is:
Is there a more correct use of geometry technique available for
sketching an airfoil symmetrically?

Using a spline, seems to be too much work to get the morecorrect result.
(at least for the leading edge)

Any suggestions?
