Patchy and Flipped Sweep Issues

Hello All. I’ve been reading up on sweeps and started playing with them. I’m having issue with the sweep completing an entire… sweep… I get patches and flipped geometry. See attached. Any help is appreciated. Thank you!!!

Not sure what the benefit of this approach would be over an extrusion / fillet approach…

Anyway, I’d try to at least put the section on the rail…

If you can’t get it to work, as always, post a file with the relevant geometries.

Or, forget about the fillets and use SubD:

Less interested in building a guitar out of this method and more just curious why this particular sweep doesn’t work. Just seemed like it the profile should sweep along the rail with no issues. Will play around with it bit and repost the 3D file if I continue to have issues.

Thanks!

can you post this file?
