Some of you may recognize this bottle. I have drawn it in a surfacing program (Rhinoceros) once before. However the program did not understand what I was trying to do. Now that I am learning SolidWorks I drew it again, and this time the program knew what I was trying to do!
To help better understand How the bottle is made I have a section view bellow. There is an insulating layer of air. This space could also be a vacuum for even better insulation.
