          1. Draw path.

          2. Apply 3D effect.

          3. Apply transparency.

            To get to Transparency, click on the menu bar at the top Window > Transparency (Shift+Ctrl+F10) and it will give you the Blend Options and Transparency.

             

            You can also use Styles (Shift+F5) to apply pre-made style effects, like Glass / Plastic / Chrome et al.

              Transparency is an all-or-nothing thing. If you are trying to simulate a bottle, there’s no way to make the back show through the front. The entire bttle is treated as though it is opaque, but printed transparently as a flat image…

              Notice that you can see the transparency grid through the bottle, but you can’t see the inside geometry through the front of he bottle.


              Getting a clean, convincing effect of the interior of the bottle as viewed through the front will involve at least one other shape, not identical to the first and with different viewing angles.

                When you are in the 3D effect window, make sure you have Draw Hidden Faces checked.


                When you have your object rendered, Expand Apperance then ungroup.

                 

                You have to manually group together the "fore" and "rear" portions. Then you can apply transperancy to both groups to acheive a glass like effect.

                  ...and no disassembly required.

                      As you can see:

                       

                      • Individual surfaces do interact transparently; even inside and outside surfaces of the same path.
                      • Mapped Symbol is opaque and interacts correctly with the translucent surfaces. (Symbol can be made to assume transparency of the surface to which it's mapped by turning on Shade Artwork.)
                      • Different transparency can be applied to separate paths within the same Revolved Group, and/or to individual Strokes and Fills of the same path. (Rendering aberations are likely, depending upon geometry.)
                      • It is not necessary to expand, ungroup, etc., etc. (The Revolve object below is still completely live and rotateable.)
                      • In other words, Opacity can be applied at the Appearance level or the object level, either before applying the 3D Effect or after.
                      • Also, Draw Hidden Faces is turned off in the drawing below. (Faces are not hidden if they are visible through a translucent surface.)

                       

                       

                      Making something "look like glass" however, involves more than just applying Illustrator's 3D Effect to translucent paths (and can be rendered with or without 3D Effect; and with or without transparency effects). Convincing glass rendering is like convincing rendering of any other shiny surface: It involves judicious drawing of highlights and reflections, not just one-click, instant-gratification effects.
