nx e reverse engineering con files stl

[Nicola21]

good morning to all are new of the forum but I use nx for 15 years, besides solidworks, catia, creo, solidedge. . .
today the company where I work and where I use nx9/11 would like a 3d scanner to implement the functions of the style office.
the scanner provides a math in stl format, which I amount in nx but can not use it in reference for example by intersecting surfaces and planes, leaning on points to track profiles, on which then build surfaces and create a solid parametric. I can maximise the profiles but the accuracy is poor.
I wonder if in nx 9/11 there is a way to obtain consistent references from which to build profiles, sections, from which to start to create manageable surfaces.
Thank you.

It is not very clear to me what you say, in the sense that an account is reverse engineering proper and that is, stl manipulation and reconstruction of surfaces from the same, another account is to make sections from which to reconstruct later of the manageable surfaces but that 'we look like'.
place an image where you can see the reverse engineering module (nx11) and its commands.
some are active with basic licenses while others require larger licenses.
you can also see a loaded stl as convergent body on which you can make boolean and sections.
If you want more precise info, just ask.
Hi.

Let's say that the maximum for me would be to convert exactly the stl that comes out from the 3d scanner in step or iges or x_t and then have a solid to parameterize and change eventually, but I don't know if you can do... I would like to understand if in nx there is a way to manipulate the stl and rebuild the surfaces or to obtain sections, sketches, guides and splines to shape surfaces. in my nx9/11 the reverse engineering module is not there, can I possibly integrate the license?
the alternative for me would be to recalculate the "image 3d" of the stl and to reconstruct everything but with poor approximation.. .
Thank you.

I don't want it.

basic commands are on all nx licenses just display the module

Thank you.

the curved comado section (not intersection I recommend) works on the stl and creates sections that you can approach with spline or sketch.
I assure you, because I did, that with a basic license you can do almost everything.
to see what license you have to go on menu>help>about nx>system information and where there is written bundle in use see license.

Hi.

Thank you so much! I have enabled reverse engineering and I'm trying the commands, basically with rapid surfacing I can reconstruct complex surfaces like a face or hand!

Thank you.

in the new releases you have the reverse module and all the convergent part(i.e. use stl almost like it was a solid)

Hi, the thing is not easy, I have a geomagic capture scanner and like cad solidworks. Lot for years to get good results that are never perfect at the penny and to get there you have to work on a lot of time. If you want to lighten your ideas a little and then apply them to nx I don't know, look at this video

I don't know what to suggest. Good luck.

As you have rightly answered, the "conversion" is not made by any cad.
but it is a basic problem on the type of geometry, in fact stl is basically the step after importing the cloud of points, where the system performs a triangolarization (forgive the term) of the cloud.
In essence, it returns a pseudo skin formed by triangles . according to the scanning tolerance, you will have more or less triangles .
of course the stl files are born to be used in the prototyping field with 3d prints where the slicing of scans allows to approximate the scanning error a lot.
for a design use it is necessary the manual intervention of the designer who " knows what to do" and above all knows how to understand/recognize which can be a scan error or not.
