Further inspection I noticed small division lines on neck profile surface that needs a rebuild.

When I set up first neck profile, the match curve extended past the outline, creating this miniature hump in the zebra analysis. I noticed the profile was bulging out past outline and my top surface of neck was not on original guideline. Which is fine, I ran so many commands that it was inevitable that somethings would move. It’s bad design when you have to use the dirty “JoinEdge” command when closing naked edges.

Shouldn’t take too long, since I know exactly what to do and not experimenting on how to design it rhino. Good practice anyways. Since I moved the neck up for zero tilt, I have to relocate the original fret2find outlines. using the “What” command I can find how much I moved it off z, which was exactly .204″. Used “Setpt” command to set z of outlines again.

Also setting the nut properly. I used the “Extend” command to extend outlines. I created the two nut lines to 4mm thickness with osnap set to near. I eyeballed it last time. Should be tighter this time. I think I may choose to move that first neck profile back maybe a quarter inch to give the network surface more smoothness. Another idea might be angling the neck profile, may be trickier, prolly set cplane to 14 mm box guide. Have to be super precise with the Nut, everything follows it. Highline guitars was right, a fucked up nut, fucks everything up. More important than the neck joint or finishing.
