Make Spiral Lamp on Solidworks 2013 (Amazing Solidworks Tutorial)

              To make spiral, you can make a spiral path with open Features --> Curves --> Helix and Spiral. And then those path is given on swept boss/base. 

                   On this lamp, I made double spiral and then joint them on top of lamp. Give appearance and then render. So this is my lamp.
