Note: If the selection is attached to other geometry, then it automatically turns off when you create a component - always check that it’s checked/un-checked as you expect.

(I have been caught out too many times by this - I now create a group [ctrl-G] and turn the group into a component [R-click].)

Yes. It’s a very good thing to check it. With SU2016, however, SketchUp remembers the state of that check box so you’re less likely to have a problem. Here it is automatically checked because that’s the setting I made back around the time I first installed SU2016.
