I see what you mean about the rebuild. I'll definitely have to remember that.

As for generating anything naca related, I'll be dependent on the other program for that. They have a large database of profiles built in. It's amazing how many variables there are, and how much they effect the function of the propeller. Fortunately for me, this is more for fun than actual use, though I could potentially make a prop to use.

I think I'm past this particular hurdle, but there will be more I'm sure. CAD has always been a struggle for me, but at least MOI makes it much less painful.
