Q1- ISOLATE SELECTION- I have 50 objects in my scene. 45 of them are under various styles and hidden. I have 5 objects visible in the scene. I then select one object out of the 5 and isolate it. If I then execute the command again it ends up showing all 50 objects instead of the only 5 that were previously visible! I just want it to show the last 5 objects that were visible in the scene and not all 45 that I had hidden using the eye icon in the styles.

I tried thes two codes...
script:moi.geometryDatabase.hide();
script:moi.geometryDatabase.invertSelection(); moi.geometryDatabase.hide( true );

Thanks
