Quite by chance, last night I was actually doing the CAM stuff for a very similar model to yours - a series of more-or-less rectangular "things" - so i was fresh in my mind. To give you some idea of what I mean by rambling - I've run some online tutorial sessions, along with a few colleagues, for my model engineering society. I think I probably took a bit over an hour to cover the kind of ground that a typical Youtube video would cover in a few minutes. I believe that there are a few basic concepts which you really need to get under your belt before you can get the best out of the product which are seldom explained, and sometimes are ignored. The Autodesk tutorials are pretty good, I have to say, but I'm cautious about some of the others.

Anyway, tabs are an easy one! When you have the 2D contour menu open, the second tab - "geometry" - includes a tick box labelled "Tabs". Tick it, and another set of parameters appears. I suggest you select triangular tabs (easier on the machine) and whatever dimensions suit your job. Remember, though, that the tab height is from the bottom of the cut depth, so if you use "-0.3mm" as bottom cut height and a tab height of 0.3mm, the tab shapes will be there but cut into the spoil board! This is yet another "don't ask me how I know..." topic. You can also choose to have F360 locate the tabs for you, or select "tab positioning at points" and just click on the cutting contours wherever and as many times as you like. I can't help you there - depends so much on material, dimensions, cutter, etc, so you'll have to play that one by ear.

Yes, it is a rich product. It's probably true that most of us don't use more than, say 10% or so of its capabilities - but it can do things that some other products cannot, and as I said before, you get to know what you actually need to set and what you can ignore in time.
