Hello  
I just moved up from Rhino V5 to V7 and noticing that multiple objects exported as an .stl, becomes a single selectable item when I open the .stl file.  
If I wanted to delete or reposition a portion of it I have to explode it.  
Is there an option to keep them separate during the export?  
Thanks in advance  
Murat

Make sure this is checked on import:

Split Disjoint meshes box is unchecked.  
Attached is V7 & V5 side by side. I can select a single sphere in V5 but V7 won’t let me unless I explode it.

The box should be _checked_, not unchecked. You can also run the command SplitDisjointMeshes in Rhino after the fact. (I love phone automatic corrections)

Hello- if you get it wrong, `SplitDisjointMeshes` will sort it out.
