Help with an stl file reverse engineering into a solid or surface 5

[poolrod2]

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.

If all you're after is the 2D outline to then extrude, then in my opinion it would be easier to use and HQ image and either vectorize it with another program or just sketch over the top after importing the image into NX.

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.

Hi, all I really need is the neck radius and head and heel transition to be one surface so I can flow line mill it.

Have you tried using "Rapid Surface", in the Reverse Engineering tab (NX9+)

Hi Dave, I loaded a zip file with the stl in it, but I don't see it.

Stl files will not appear in the part navigator unless you set the navigator to "history free".
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.)

Tomas

@poolrod2 I don't see an attachment either. If you can get the file uploaded someplace, I could take a look at it.

I'm not sure how to get a zip file on here, it works on cnczone.com.

So poolrod2, you're looking for the profile shape of the neck, as seen from the audience??

[poolrod2]

All I need is one solid or one surface to machine just the neck radius areas and transitions, but currently full of facets.

 

[Dave K]

A few surfaces, in parasolid format...keep in mind, this was real quick during lunch, so I'm not sure how helpful this will be.

Dave, this might work perfect, pushing it around, trying to get it normal to the original surface, otherwise, this is exactly what I need. Thank you for the help.

Hi

Hi
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

 

[poolrod2]

Thank you for the help guys, I'm very close on this now, just have one area close to the heel that needs attention. This is from what Gunman sent me.

I gave it a try also as it seems like an interesting project as a whole.
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!

[poolrod2]

That is perfect, could you save it as .igs or .stp by chance?. Thank you all for the help on this.

 

[SS88]

Sure, no problem.
