Fusion achieved a strong presence by the expedient of giving away a level of capability that had previously cost a lot of money.It hooked a lot of users and weakened the business of the other developers and sellers of similar products.Which hindered the development of alternatives and led to the position where Autodesk could limit the functionality of the hobby version and begin to charge a modest amount for access to the extended capabilities of Fusion.Is it the best?No idea,because I don't use it but there are lots of professional users making parts with other software and even paying healthy annual charges to do so.Which might be an indication that the others do a solid job.If your anticipated use extends no further than cutting 2d shapes with the occasional hole or pocket,there are a few utterly free ways to do so.I use Freecad on my hobby machine because it means I don't have to export a file in a different format and any adjustments can be re-calculated almost instantly.It isn't the most intuitive but does have a range of post processors.It seems to be progressing faster since a proportion of disgruntled former Fusion freeloaders have moved across.
