So I tried to export a selected Mesh to .obj format with the latest BETA but export failed with the following message:

What has “closed” with export to do? Isn’t it only .stl files that should be closed?

Hi Rolf - there is a setting for that - at the bottom of the Mesh page in the export options.

Argh… Thanks for the hint.

This is yet another useless error message. My humble suggestion is to add a more pragmatic message to the “error dialog” about the fact that there’s a secret Export Option that may cause the hassle… 🧐
