I wasted an hour reading through the turning tutorial and trying to figure out why nothing would work. I could choose "Turn Single Turret" as the machine (even though, as I now realize, it was grayed out and the "Select" button was unavailable) but "Turn Operations" on the Command Manager never activated.
I though maybe it was something wrong with my settings or installation.
After some searching, I came across a feature comparison between Solidworks CAM Standard and CAM Pro on the engineersrule web site and found that turning is not included in the Standard version.
Thought I would post this for the next poor sap.
