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.

Understandable....
Have fun Rusty!

And no doubt that someone will make a Naca dynamic modeling with Elephant! ;)

"""""""""""""There are settings to change the thickness of the blade at the root and tip, then another slider for the curve between those"""""""""""""""""""
These 2 values actually relate to each other mathematically in airfoil design. The changes have to be planned.
Changing the chord length from 1 station then back again right After it within just 3 stations will be a no no....
You can check your chord lengths. They usually taper from root to tip.
I think the trick is to choose a "ratio" as a percentage of lift coefficient, then stick to that as you change the thickness or chord length (Or Both)
Choosing this chactoristic allows you to pick and choose a change you want, but maintain the aerodynamics as you go...
