Our company is working with a supplier that uses SW 2013. We currently use Creo 3.0.
When the supplier tries to open the file we sent him, he says that some surfaces are missing and it is not solid. It is a cylinder head, so it is a complex model but we sent similar models and never had any issues.
I tried to export step, iges, *.x_t and they said that the result is the same. Is there anything I can advise him to do when opening the file on SW2013? For what I read, SW2013 does not open creo 3.0 files.
