This file started out as an Illustrator vector graphic, I saved as a svg file and imported into Fusion 360. This is version two after some minor edits to create more objects. There are plenty of levels to make the piece interesting. Since this will be one of my first projects I am seeking ideas on how to cut it. Do I simply use the 3D option with roughing and smoothing operations or do a number of pocket operations or some other approach? Here is a rendering in cheery wood. Also where do I setup Z, on the spoil board?  |

I'm certainly no expert with the CNC yet, but I think your best bet to start with is an adaptive clearing pass. It takes longer to compute than any of the other operations from what I've seen, but I think it's more efficient than the others when it comes to the actual cut.
How you set your Z zero depends on how your cuts are set up. I think it's the default in Fusion to have the Z zero be the top of the work piece, not the spoil board. There are a ton of options in the cut settings, most of which have pretty informative tips pop up on mouse-hover. Also, check the videos in the "General Millright CNC Discussion" section of the forum. There are a couple of videos in there that I think will clear things up better than I possibly could.
One thing I'd suggest, as a fellow Illustrator user, is to take a look at exporting a .DXF instead of an SVG. A couple of quirks: even though I'm using metric in both Illustrator and Fusion, I always have to switch the units from inches to mm when I import, and there are occasionally a couple of paths that aren't complete (it will throw an error and highlight the bad portion - I haven't worked with SVG enough to know if it shares that issue). For the latter, I've found that jumping back to Illustrator and running a quick "Path->Offset Path" effect (by, say .5mm), expanding the appearance, and then doing the same thing but with a negative value to restore the original shape will solve the problem. Other than that, I find the import options to be much better. The biggest perk is being able to selectively choose which layers you import, and whether you want to import them all to one sketch or a separate sketch per layer.
I dig the design, btw!

If it were me, I would probably use 2D pocket operations on this one.
