There are adjustable for just about every aspect of your interaction with it.

All (well, the two or 3 models we have at work) of the enMotion dispensers have that option. It's just a switch inside to leave one out or not.

I bought a set of keys for the most common ones, and when I run across paper towel dispensers that spit out the shortest length of paper with the longest delay, I pop them open and flip the switches to give the longest length of paper and shortest delay. And fix jams and misfeeds as well if I run across them.

I learned my lesson about 'lifetime' updates with a Tom Tom GPS unit, from the late '90s, maybe early 2000s. After about 4 or 5 years I couldn't install the latest map updates, so I contacted CS. They said, "Oh yeah, lifetime means the time of the expected life of the unit, which is 4.5 years. We don't support that model anymore. Any other questions?"

Calculon?

Sorry, I don't have the slightest idea.

I don't know exactly how it is implemented, but if I had to guess, it is probably just metadata in the file. I know that when I print out the 2D drawings I make, it puts text in the bottom corner with something to the effect of "This was made with the educational version of Solidworks, Not for commercial use" or something like that. I expect something similar if you tried to open a file made on the educational version on the commercial version, there would be something similar on the screen. Not sure though, since I only have the educational version.

I use CATIA at work, and it's funny how both programs are made by Dassault, but have such different interfaces.

Yeah, I make things for me and family, but you'd be surprised at how many other people would be interested in it as well. I certainly was. I looked at my Thingiverse analytics, and I've had 10's of thousands of downloads of my things. I know those don't directly translate into prints, but I was shocked at how many people downloaded my designs that were originally just for me to organize my sandpaper, or sift sand or hold my CNC collets and wrenches. . .

Solidworks (Education version) for US and Canadian Active Duty and Veterans is US $20 or CAD $40 / year.

I am on my 7th or 8th year of it. I don't use it for making money, but use it for making 3D printed things for around the house, then upload them to Thinginverse and Printables for everyone else to use.

It looks like Solidworks for Makers is US $48 / year.

A couple of answers from the Q&A at the bottom of the page:
