Groups ungroup when exported as .stl

Hi everyone
When I export grouped objects as .stl they don’t stay as group anymore. I am saying anymore because I always thought they used to stay as a group.
Is it normal or they should stay as they were?

Thanks

Hello - if you export disjoint meshes, grouped or not, as stl, they should be one mesh in the stl file. If you open or import stl files that have disjoint meshes, you get to decide whether they are split or not… dunno if that makes sense with what you are seeing. (Groups should not enter into it…)
