Hello everybody, I’m completely new to Rhino (and really CAD in general) as of this week, so I apologize ahead of time for the numerous issues there likely are with my approach to design here. I’m attempting to create a banjo neck and I was very loosely following the methods applied in a Rhino guitar neck video I found on YouTube by Helix Guitars (https://www.youtube.com/watch?v=wLaPAeKPuqA&t=2016s). I never could get the network surfacing he was demonstrating to work, so most of the surfaces are patch surfaces or surfaces from 3 to 4 curves.
This first picture shows the basic design (ignore the weird horn shape at the end as it’s supposed to be a step in the process towards making the neck volute transition). The arrows are just showing where I placed neck profile curve drawings to define the neck shape.
This is the side of the heel transition and it’s dipping inward from the neck profile. I’m trying to figure out a way set a limit somehow, where it cannot dip below/inward from where the neck profile would have been if it continued through the heel.
This next picture is the top of the neck’s heel portion, showing this weird peeling effect I’m getting, where the patch surfaces don’t exactly line up with my curve drawing, and hence, not with each other either. I’ve tried showing object control points and tweaking them, but it’s always an unsatisfactory compromise, not following the original profile drawing directly.
The final picture here is showing another way in which the surfaces are just not following the profile curves I drew, and how they misalign unless they’re continuous. Even if I could make these continuous though, it’s concerning that they’re not directly following the profiles I’ve drawn.
I would greatly appreciate any help you all can provide. I’m trying to design CAD models to machine from hardwoods on a new CNC router I’m having made. I really want the designs to be exacting to avoid needing to correct any geometry by hand after the fact. There’s a ton to learn with Rhino, but I’m hoping I can figure this craziness out! Thanks for your time in reading this.
