Export selected facets as .stl?

I like the feature to export selected facets.   Would it be possible to export them as a .stl file?   As of now they are only exported as .geo.   many thanks

Hello Keng-Pei,

As STL format doesn't support polygons (only triangles), this is unfortunately not possible.

Thanks for the quick reply

If my file started as .stl, and I didn't combine or collapse any points when it is imported, would this keep it purely triangle and safe for .stl export?

Hello Keng-Pei,

Yes, if the original file wasn't collapsed, exporting it in STL again could work. But it needs time to write this new function, and many geometry editors already do this. So I was wondering: what exactly are you trying to achieve? Why don't you save he parts as geo files?

Hi Marton,

You are right, I've tested several 3D model editing tool and did find a couple that do the job.   Thanks.
