I totally disagree. I do agree that F360 isn't TOP TIER professional, the likes of Inventor or Creo or ProE, etc. But plenty of those compete with Solidworks for the professional dollar, and I'd buy Fusion 10 times before I'd buy Solidworks once - as many in this space have.
I think the differentiation is pretty analogous to Eagle vs TOP TIER professional EDA software - nobody evaluating "Allegro vs Altium" thinks "but what about Eagle?" But PLENTY of companies doing legitimate, professional design work just don't have design or business rationale to sink that much money into CAD software, and land on Eagle.
Perhaps I am a good example along with many of the companies that I work with.
I used Solidworks since 1998 along with Mastercam and Camworks. All of which are expensive, professional packages that have a lot to offer. About 2.5 years ago, I was faced with the annual maintenance of Solidworks and Mastercam which was about $3k plus the penalties for skipping previous maintenance coming to about $5k.
I decided to try Fusion360 on a trial to see how it goes.....it went great. I transferred a very complex and very expensive product design with about 1,000 parts over to Fusion. It is a tightly integrated project with a dozen+ circuit boards wrapped in a complicated CNC machined enclosure. The sale price for the product is around $20k/ea and sold to very high level businesses that accept nothing less than perfect.
Fusion easily handled ALL of the mechanical design, CNC machining, documentation drawings, marketing renderings and animations. At that time, there was basic integration with Eagle that allowed a very fast workflow to identify and resolve conflicts with EE and ME.
I never looked back. I love Solidworks, but don't miss it for a second. I love MAstercam, but don't miss it for a second. I only made one project in Altium and loved it - Eagle is still quite a distance from Altium but the integration workflow (separate Eagle and Fusion360) is FAR better than Solidwoks/Altium. The F360 integration has a ways to go, but they are making steady progress.
Many business exclusively use F360 and Eagle because they were accessible when they were small and they don't want the learning curve and expense to change. I spoke with the Altium sales person yesterday and told him that to switch I would drastically increase my software expenses, require a huge transition, a big learning curve and the result would not likely be any better from a business perspective.
I design high layer count high-speed impedance controlled PCB's all the time - all of which are somehow integrated into a complex CNC enclosure or requires some complex thermal control design. Fusion360 has simulation tools to help with cooling designs for electronics built-in.
I am not going to burn money on higher end tools just for bragging rights.
