Just to set expectations, I don’t think there’s a straightforward “SolidWorks for Nomad Dummies” that you could use. I think the overlap between SolidWorks users and Nomad users is quite small, as Nomad is a hobby machine and Fusion 360 heavily dominates among hobbyists due to the free option.
The best help I can give you is the post-processor for SolidWorks CAM, which will be 100% necessary for exporting G-Code.
Aside from that, you’ll have to set up the machine in SolidWorks (which should mostly be a matter of looking up specs) and find some comfortable feeds and speeds. If you’re working with metals, the Nomad (at least the 883 Pro, it wasn’t clear which Nomad you have) can be quite picky about those because of its puny frame and spindle (relative to the machines your pros are working on), so I’d recommend looking at Winston’s fantastic MaterialMondays videos to get an idea of what feeds and speeds to use.
All that said, you can also just use another program for CAM, like MeshCAM or even Fusion 360. You’ll have more resources available that way.
