Congrats, Charles! I am very excited on your behalf. There are so many toys to play with in this program, such freedom to try new ways of doing things because it is literally "no sweat" to modify one's machining methods, once you get a good model built.
I won't say its dead easy to make solid models, because that requires a new way of drafting (for us old Bobcadders, anyway). However, a solid model (or a relevant surface) is a gold mine of useful info that makes the rest of the program work as good as it does. Dig right in!
First you get good, then you get fast. Then grouchiness sets in.
