Convert Solidworks files to neutral files

Hi all,

May I know if anyone had save SWX file as a neutral file and open it in UniGraphics before? 

I have one customer says that previously when he save SWX files as a neutral file and open it in UG, sometimes some faces would be missing and the whole solid would become a surface model. However, when he save a ProE file as neutral file and open in UG, it was always a solid. Thus, he was asking if Solidworks still have this problem now. As my side does not have any UG or ProE seats to verify it, I'm asking if any one here has done this recently.

Thank a lot.

Best Regards,

Mi Le
