All, 

I'm trying to create an airplane interior.  I can use downloaded .obj files for the seats etc.  However, for the outer portion of the plane I'm having a little difficulty.  The hallow tube works in a pinch.  But one can make it transparent.  Is there a way to make a half hallow or cylinder or tube?  

Also, how do I place transparent windows into the tube?  

Any suggestions are greatly appreciated.
