Possibly. If it is AutoCAD or some standard tool (perhaps not a model airplane wing unique tool) then it should have an area function. Just like solid modeling tools (ProE, etc.) have automatic volume and mass properties functions. (Center of gravity, mass moments of inertia, etc.) And, another feature that is helpful with odd shaped wings is the centroid function. If you are actually designing an airplane instead of morphing from existing designs and counting on it working, you will need to find the MAC. A CAD tool is most helpful with the engineering tasks, and somewhat helpful with the drafting tasks. But if you put in a large amount of effort to design in 3-D, you get a lot of the "drafting" for free. Snap as many views as you want. Sections, too.
So if "one potato, two potato" squares can work for you, and cardboard can work for Floyd, can we at least agree that formulas can work for Motorman, and two pins and a piece of string can work for someone else?
