Hey @jay443,
This thread may be of interest ?
To kickstart your 3D adventures you could pick one of the ideas there, and try to reproduce it ?
The important thing is to understand the workflow (which is relatively simple). After that, cutting a very simple 3D shape or an arbitrarily complex one are not very different, because CC Pro does all the work, when you tell it to generate a 3D roughing toolpath, and then a 3D finishing toolpath.
Pick an idea of something you would like to do, and if after watching those tutorials you don’t know where to start, report here with your idea and we’ll help.
