And if the programmer is really good it can be done in a fraction of the time than doing it by hand. You can twist and tweek surface profiles anywhere you want on a CAD.
But theer has to be material to work with to change the profile on a cnc but I thought some props ears were worked, call it bending if that is correct. I guess my point was, I hope that knowledge isn't lost or does the guy making the cnc prop retain the knowledge to make the tweek . If I have prop"A" and say I need more lift for example who does he call to find out what program to run to get that.
