Thickness of airfoil

Question asked by C. Y. H. on Oct 24, 2016

This chord length for this airfoil[NACA 4415] is 0.567m with 42 beta twist angle: however,when I tried to use offset entities to make this airfoil thickness to be 0.383m, it just said my dimension are too big. Do I have to scale down the drawing in order to work out the thickness, First I will make the whole airfoil solid, then I have to scale it down to eg: 1-(thickness/chord length) and extruded cut it?

Any tips will be appreciated!!! Thank u in advance
