hmm,

i'm having issues with the radius using three point arcs. when i go to fillet it blows up. i'm going to have to work on this a bit more. maybe adjust the points so a two point arc works. i think if you use a three point arc for the le and a two point for the te it will work but haven't tried it yet. otherwise i will adjust the points so you can use a two point arc for both and make it simpler.

edit; after trying a bunch of options including modelling it with the last update of prop_design_geo, i'm thinking the problem might be a smaller te radius. the updated naca file had a slightly smaller radius. when i Boolean union the hub to the blade the te blend is messed up (missing a curve that should be there).

i'm going to try putting the te radius back to the other definition i had and see if that fixes the problem. i will leave the rest of the updated definition in tact, as that fixed a lot of other issues. i want to look at the le points i added too because i'm getting that same error brian found before where the chord is a little bigger than it should be unless you use a three point arc.

update; it wasn't the ter either. i'm stuck right now. the Boolean doesn't work right now. i'm not sure what is causing it. i'll have to get back to you once i figure out what is going on.

update; ok its working. not sure what the issue was. must have been how i was joining the curves or the sweep options. it works with the updated geo. the only thing i want to look at is why the le arc is a little off with the two point option. there is a small error somewhere. i'll have to re-measure and calculate all the points and see if a few are off a little.
