Exported STL has 0 KB


Updated by Altair Forum User
Hi,
I used OSSmooth to Import an Isosurface into Hypermesh from a previeous optimisation. I want to export part of an assembly to stl, so I can't directly use the export from OSSmooth. When I create the faces from the 'find faces' panel and try to export as stl. The resulting file is created but has 0 KB and no model inside.
I don't know what I can try to resolve this issue as there is no error message.
