Extrapolating a Smoothing

Hello

 

I'm starting with Solidworks and I'm trying to model a guitar neck... I know two sides and I try to extrapolate the third one with the "Boss/Smooth Base" function but I can't

so I have the profile of the nut plane, the one of the "fret 12" plane and I would have liked it to continue the extrusion up to the Micro plane while keeping the angles and dimension calculated between the first two planes.

 

Is this possible?

Thank you

If you are on the surface, you can extend your surface to your plane.

otherwise, you create sketches on the planes perpendicular to those depicted. The sketches go through your known and continuous profiles to the desired plane.

This allows you to draw your last sketch on the last plan.

And do your smoothing.
