We have a bit on this here: http://carbide3d.com/docs/fusion360/
That said, unless you have experience with and a real, driving need for full 3D machining, I don’t recommend adding in the complications of a 3rd dimension pervasively at the beginning, it’s a needless complication.
The nice thing about Carbide Create is that it’s as simple as it can be (sometimes frustratingly so) — a bit of experience with vector design helps w/ understanding it (though makes some of its missing features agonizing) — more importantly, by only providing the essentials, it allows one to be exposed to only what is needed to start, greatly simplifying early success. If one has experience with another drawing / design tool, then it’s an excellent strategy to do the design in the familiar (and more capable) tool and then import it into Carbide Create for CAM. That said, the user guide for Carbide Create is quite brief: http://carbide3d.com/carbidecreate/userguide/ — I’ve tried to expand a bit upon that on the wiki: https://www.shapeoko.com/wiki/index.php/Carbide_Create and https://www.shapeoko.com/wiki/index.php/Carbide_Create_Basics
More importantly, the concepts and terminology which you will learn while using Carbide Create will apply to any CAD/CAM tool which you may work with later.
Learn the terminology, do a couple of basic tutorial projects. As a crash course I would suggest:
- http://carbide3d.com/carbidecreate/video/ — look up any terms which are confusing at: https://www.shapeoko.com/wiki/index.php/Glossary
- Let's make a coaster — this covers the basics
- http://carbide3d.com/docs/tutorials/shapeoko-clamps/ —you’ll need clamps anyway — get the file for this from: Bamboo Work Clamps made with Carbide Create
Once you’ve got the basics, then you can move on to more interesting (and complex) things.
