hi burrman,

the naca points stop short of the leading edge radius. this is the problem really. if they extended out enough then you probably could have some sort of shape that you could then fillet after the fact. but you can't have a smooth continuous spline without a few extra steps. i have a screencast showing how i do it. you and michael actually helped me determine that process awhile back. it works great. i have no problem at all doing it manually. i just thought it would be nice for new users of prop_design and moi to have a script. its asking them to learn an aweful lot without it. you have to learn prop_design and moi and then figure out how to model the blade in moi otherwise. this way its a lot easier on a new user.
