select all visible objects? I have a model of a vehicle that contains a ton of objects. seats, seat belts, etc down to individual screws and such.  All I want is the "skin" really but not sure how to do it.  Is there a way to quick select all visible objects ignoring what i cannot see?

Thank you for your time/help!
Select everything visible with the lasso tool ( ctrl ), then inverse the selection with ctrl i, then X to delete.
