As a reference:
I initially paid about $10,000 for Solidworks in 1998 plus about $1200/year in maintenance. I skipped some years.
When I needed CAM, I had to spend $13,000 for Camworks as an add-on to Solidworks.
Camworks sucked, so I spent $15,000 for Mastercam plus $1400/year maintenance.
Then I needed high quality rendering so I had to pay $1500 for 3rd party rendering/animation
When I needed to add electronics, I was using Altium but on one of my customers license. I ended up just getting Eagle when I needed to design my own circuits/PCB's since Altium is $10,000 plus $1000+/year for maintenance.
As my buisness grew over the years - I had added 2 additional seats of Solidworks and one more Mastercam.
The numbers were staggering.
All of this is included in my Fusion360 subscription for a few hundred per year with no up front costs. A massive cash savings.
I have chosen my battles and Solidworks/Mastercam/Altium lost. $30k total plus $3600/year for maintenance updates. That is a LOT of money for software that is only slightly better than the competition that is a tiny fraction of that.
