Hello guys, is there someone who can help me turn a mesh into a .stl model? I should use as software or catiav5 or geomagic design x. thanks.

depends on what your final goal is.
all cases have the possibility to import a neutral file, but as such it contains only geometry.
There are options for automatic recognition of features if you want to get a complete parametric model but I have never heard of great results if geometry is no longer simple.
If geometry was simple, quickly remodel it. If the geometry is complex you should remodel it because the result of the import would probably not be satisfactory.
if you have to import and make "only" some changes you can do

hi, reverse engineering can be very complex. What do you have? first you need that to import the sl correctly (in reality there are two that do it, one is called typazed shape something... the other shape sculptor or something similar). then to make surfaces and geometries on mesh you need the qsr module (quick surface reconstruction). with this module you can "isolate" portions of stl and make them create automatically or elementary surfaces (plates, cylinders, cones...) or freeform surfaces. with this module, moreover, you can also realize network surfaces from curves drawn directly on the slate (but I never use it... I think it's too turkey and the result is very much to be desired. . . ).
However it depends on the type of geometry you have to achieve. Can you post an image of the sl? to make simple mechanical parts you can also switch from the gom viewer, gom inspection which allows you to create on the slate floors, cones, cylinders imposing constraints of various types (normal plane, cylinder diamtero, axis direction, cone opening angle) in a very fast and efficient way. Once you create these geometries you can export them to iges and to assign them to pleasure.

I am in a condition in which I should reconstruct (or at least improve) a complex surface (frame) . I was looking at the form catia - reverse engineering but I seem to understand that you work on clouds of points or twelfths and, even for that said earlier, should not be the right way . I have a surface full of defects (overpositions, nodes etc.)
Thank you.
Thank you.

Are you referring to the slate? You should try to editate it to make mesh congruent. . you can try the software I indicated before, of the gom (producing machine scanning both optical and tomographic). have a free viewer that could do for you. Although it is "only" a viewer allows you to do a lot of things, even edit acquisitions. . .I am in a condition in which I should reconstruct (or at least improve) a complex surface (frame) .

No, actually, I only have a surface resulting from a statification process whose result (complex) provides overlaps and "pasticci" in various points. I was testing the catia module to try to improve the whole but it doesn't seem to me the right way (even if I might be wrong given the lack of use I made of it) . I asked if any of you had experience of this type and how to solve it in order to have a final use .

Hi, Vito.
Usually if the surface is composed of several patches it has several problems, you could separate in the various patches and rebuild the damaged ones and finally join them again, but to find a strategy you should see at least some image

in addition to quote in toto what he wrote gianni, I apologize for misunderstanding, but here we were talking about reverse engineering on stl, not repairing corrupt models. . .No, actually, I only have a surface resulting from a statification process whose result (complex) provides overlaps and "pasticci" in various points.
