I've tried to gey my head round Fusion360 a few times but it just doesn't seem to work for me either. I've used CamBam since the first day I switched on my original MDF and allthread machine and am still very happy with it, especially with the huge range of useful add-ons available from the very active support community. You have to pay for it but it's a one-off payment that gets you a lifetime of updates.
