SU 2015 Where's 3D Warehouse?

I recently downloaded SU 2015, but the 3D Warehouse option/icon didm’t come with it. How do I fix this?

I don’t thnk anything has changed as such but you’ll find the Warehouse toolbar several ways.
Go View/Toolbars… scroll to the bottom and tick Warehouse.
or
Right click on any existing toolbar and scroll to the bottom and tick Warehouse
or
go File/3DWarehouse/ Get models etc
