Help with an stl file reverse engineering into a solid or surface
(OP)
Hi everyone, I had a guitar neck digitally scanned for my daughters school project, to machine it on a router, but no matter what software I try, it comes out as patches of surfaces. Is there a way to make it just one solid or surface as if it was extruded from a 2d sketch?. Thank you all, any help would be great. stl and bad model image attached.

I like using Inkscape to vectorize (see https://vimeo.com/83654051 on how I do it).
Otherwise, cut sections through the STL and use that as the basis for what you're after.

It should be visible in the graphics.
Stl files will not create solids but " a faceted body". - Which you can section etc.
If you have NX11 you should be able to do some solid modeling operations on that faceted body.
( NX 10 & earlier cannot do solid operations on facets.)

The above file illustrate a way to play with
view section save curves it requires a passion
you can save section curves in small steps
And then use surface through curves to build
a solid

Might be that you don't need it all anymore but it was good practice with the reverse engineering tools while trying to keep the surface quality adequate.
Good luck with the project!

Can someone use the cyan curves(see link) to build the guitar solid
and show how
Thanks in advanced

What are the steps in using the reverse engineering tools? I have never used them.
Thank you!

Any chance you could create a quick video so I can try an figure it out?
Thanks again!

I can share the NX file, note that I've done it with 11.0.1. I share couple pictures of the surface pattern to get the idea what I was doing. I don't know what is the best way to create the pattern, this way is what I've learnt with trial and error.. Basically loose pattern/web where high resolution is not needed and thicker web where resolution is needed like in the variable radius areas in this model. I would be more than happy to receive any tips or better ways to use Rapid Surfacing also.

@gbangs cranking it to 11 makes even more sense with a guitar neck!!

When surfacing, the aim should always be to create as simple as possible surfaces / faces.
Creating the entire neck in a single surface is fully possible for surfacing artists, but the result will be a highly complex and heavy surface which might not be usable for downstream operations. - Don't even try.
A single feature might contain almost any number of faces / surfaces, all hopefully as simple as possible. The resulting model is smaller ( MB) , faster and usable for downstream operations.
