Different sketch design for top and bottom of a body for a loft

[disconnector]

Hello all!

I'm just learning F360 so please be gentle . . . I'm noobish but learning fast!

I'm trying to 3D model a guitar neck for CNC milling and the headstock volute is giving me a difficult time.  The back of the neck lofts just fine but I'd like the top to loft to a different point.  The screencast attached might be helpful.  I've also attached the F3D file if anyone wants to check it out.

Screencast URL - https://autode.sk/2J16GcV - the Screencast attach isn't working for some reason.

I've cut out quite a few necks and bodies as 2D objects and just hand shaped them.  But I feel like that's chickening out when I have a 2.5D capable CNC router.  This is my first attempt at creating a true 3D neck with 2 sided CAN tool paths.  With the exception of this problem it's working fairly well.

I'm sure this is super simple - but I can't figure out what to search to solve the problem!  

Thank you!

Rich

I have not had a chance to look at your design (I'm supposed to be paying attention in a meeting).

Don't feel bad, this is anything but easy.  Guitar neck shapes (in particular these transitions) have generated a lot of discussion on this forum.  Check out these threads:

Hope these (or their authors) can give you some good hints!

Omg. I didn’t search guitar necks because for some reason I figured I was the only guy/gal doing this. Apologies for the post - I’ll read these links. Thank you!!
