welcome to the forum
Take a look at the tutorials. They really help. Some for WTP are dated and do not cover the changes in the program with the updates Lloyd did.
I have all of Lloyd's software.
WoodTurner Pro gives you the most control on design and each ring.
Segment Pro is more rules based and automates a lot of the design for you, but limits what you can do with each ring.
They both make it easy to make changes and the cut list is updated.
Ask your questions and someone will try to answer them.
