The industrial strength 3D modelers like Solidworks, Inventor, Catia, possibly Onshape (not 100% sure there) are all big bucks. SW guessing 4K for licence + 1K maintenance. They may vary by promo or term commitment or lower upfront cost vs higher fees, modules/capabilities etc. but I suspect its in that range. Hard to justify for 'hobby use'. But that enters the slippery slope domain when dollars meet leisure activities. Usually its a spousal conversation - Do you really need that.... [shotgun/golf trip/milling machine/shiny car part/purse/handbag]? The answer is inevitably Yes. Who am I to judge? haha
So if you say Fusion is 80% of SW capabilities, then its still cheaper by a long shot. Which is why I pretty much predicted this price bump several years ago. I just cant find the post LOL. I think this was part of a long term business plan, or possibly the plan has been amped up to get more cash flow in the door just like Microsoft & Adobe & all the other subscription platforms. Strange thing about investors & shareholders - they like constant, predictable & high revenue.
I was kind of fortunate (if you can call it that) I did some mold related work that essentially paid for SW licence leaving me only <cough> the fees, which were also less back in the day. But renewal time is not a welcome date, I find it an ever increasing tough pill to swallow. OTOH I use it daily & it would be very difficult to build my radial or future projects like it without this level of software, so like it or I will be married to 'something' until the machines also roll out the door. Some guys come to a point where they go coast mode. They just stop renewing & simply use that version until it becomes redundant. Your files can be read by newer version but no support. I know a guy doing this running SW-2008 or so, but he is also buying antique PC's with locked down OS & backup systems. This is the last year SW is supporting Win-7, so OS & PC power is another consideration with software.
The only outs I've heard for SW is
1) veterans, you know who you are
2) joining EAA (experimental aircraft association) which gets you a working version. I'm shocked by this actually & really keep meaning to look into it. I don't know what membership costs or what is entailed to being a member in good standing. But that is my retirement strategy - volunteer doing something I'd do anyways & get some software out of the deal.
3) academic. I think SW is very fussy about compliance; transcripts, full time academic program, specific recognized programs. This was also confirmed by some engineering interns I spoke with. SAIT doesnt do SW I think they are Inventor? And it expires as soon as you are done your program. It has varied over the years but I think that's the norm. Once upon a time it was cheaper to take an evening/correspondence course just to get the software. I knew photographers that would take entry level Photoshop courses just to get the $$ product suite. One guy ran out of courses so re-enrolled & started again citing 'learning difficulty' LOL. Well the software vendors have tightened that up & they are on the lookout for repeat names, same address (son or daughter), CC#. Plus evening/correspondence courses are getting stupidly expensive. Why pay Sait $500 for a 40 hour 3 month course vs pay Adobe for a year & train on Lynda for free?
Back to Fusion I was seriously looking at 2021 as being a transition year to at least learn it so I would have my own perspective of what it could & couldn't do for my own needs. I still might but I think the writing is on the wall.
