Just as a practical example, how would I model this?

http://www.baccarat.com/en/home-decoration/arts-table/verres/HARCOURT-SERVICE/product/HARCOURT-SERVICE-CLEAR-CRYSTAL-GLASS--.htm

As I see it, there are 2 "challenges":

-Going from 6 hard edges at the bottom and various parts along the glass/profile, and:

-The 6 "grooves".

Thanks for any tips/responses!
