Hi Burrman,
Damn, really sorry to hear about getting cancer. That's terrible. I hope you are able to beat it.
Yeah, the mountains of math is the hard part. I'm still finding bugs with PROP_DESIGN. I started with a code called PROPSY, thinking I could scan it it and it would just work. Damn, was I wrong. 10+ years latter and still pounding on it. You helped a lot with figuring out the leading edge was an ellipse. That was not clear at all from the NACA definition.
At various times, I asked if a script could be made to automate the geometry creation process. Some progress was made but don't think a finished product was posted. However, that helped me find some important bugs as well. So it was helpful.
Yeah, I hear you about forum posts regarding accuracy. A lot of the work flows that seem to be popular aren't something I could use. Even a loose loft is not an option. So I just kind of shut up as well. Just easier that way I guess. Plus I saw what happened to you. I couldn't stand that guy either. Naming lofting after himself. The arrogance was unbelievable. Yet he was a popular user. So that left me pretty dumbfounded.
I started with a 2 rail sweep using 1 profile. I ended up finding out Rhino was screwing up the geometry. Even small deviations had big impacts on stress and vibration. You would be surprised what a small deviation can do. Eventually I figured out lofting with multiple profiles was the best way to go in my case. That ensures the aero and structural performance.
