Exporting faces problem

Hey guys! When trying to export this object, its giving me problems with some surfaces missing when opening the file in obj. Do yo have any idea of what could be causing this? also tried other formats and it wont work :frowning:

The model has at least two very small surfaces which might cause some tolerance related problems…

There are a bunch of surfaces and open polysurfaces which should be joined before exporting.

You can select closed polysurfaces and then one after another try to fix the remaining parts. I’d isolate a part and explode it to delete what’s not needed and maybe trim some surfaces to be able to join and finally try to cap or in the worst case rebuild a part with clean curves.

I will try that. Thank you for your quick reply :slight_smile:
