We regularly receive 3D models from WWTP subcontractors.
When you do the conversion in SW, 3/4 of the time you end up with a surface model and a lot of reconstruction errors.
How can we avoid this problem? I know we can change a few settings in the options but I feel like that's not enough?
Import diagnostics are also a solution but cumbersome to manage, especially when you don't have a good command of the surface area.
Meric in advance for your help.
Apart from the import diagnosis which allows in most cases to re-examine the surfaces in volume via "Tried to repair everything", when it doesn't work I convert the file back to STEP once again or to IGES and it allows in some cases to remove the problem.
After that, I don't think there's a miracle solution...

If your subcontractor has generated his step in surface you can't do anything, the best thing is to ask them to export in volume step, if possible.
Otherwise you can thicken surfaces, or other method, but nothing very easy.
Even wastewater treatment plants generated in volume sometimes fall back with surfaces following a transformation problem. Of course, if it is created in pure surface, then I think it's dead, unless you rework the surfaces to try to fill or thicken but it can be very difficult or even impossible.
I tried to re-record in IGS, STEP and PARASOLID.
Nothing helps, always the same result. I asked my subcontractor to send me back the 3D model in PARASOLID. In general, I have fewer errors.
In IGS, he created a 3D sketch of one of the sets, it could be a solution for small parts but for large ones, I don't even embark on the adventure.
Unfortunately, first of all, simple and surface rarely go together, so when it's also the result of an import, I rough it up to limit the problems and then basta, it's really too time-consuming for the result obtained.
Often it is the threads and tangent faces that are the problem. The former are easy to manage: we delete them. The latter often generate commonalities to several surfaces that are impossible to solve.
This is, in my opinion, SW's downside (I must admit that I don't know the other software on this point): its inability to process step/iges correctly.
The sat and parasolid files are indeed less of a hassle.
Talent and ... patience...
In the end, my subcontractor sent me the parasolid model and the import went perfectly.
I have tried all your solutions but nothing is 100% effective unfortunately. It's true that trying to solve surface problems is time-consuming as Stefbeno says.
Thank you in any case for your answers.
