I am currently inputting a wing into Rhino from a set of plans. The plans call out X, Y, WS, and %chord. This wing has 5.5 degrees of dihedral. Is the Wing Station typically measured in planview or is it typically measured along the wing's actual coordinate system? As a result, do I need to transfer the WS measurement by modifying it with the cos(dihedral) to get the actual x,y,z coordinates I want to use?
Along the same lines, should I assume that the airfoil section given with each X,Y,WS coordinate is supposed to be perpendicular to the spar, or vertical in the x,y,z coordinates?
Below is the wing with no dihedral, assuming the WS coordinate is the z coordinate. That is that the WS is unmodified for dihedral.
By the way, I just would like to add that Rhino is really nice for modeling surfaces such as this. It's much more user friendly than Catia/Unigraphics for this kind of modeling.
