Open your software and go to the Help drop down on the Tool Bar. Look for >Check for Updates.
Since I just updated my software this morning, I am still learning about the new features myself. So the first step is to find the videos located in the opening screen. I was slightly confused because some of the videos said Build 3217 but the actual Build is 3224. Perhaps it is just me, or not.
They are 6 of them and they are listed at the top and start with CNC. If you can't find them here is the link to the software videos by Hope Yoder.
It looks like a busy day for me trying to catch up on all of my updates.
