Learning a new application for something as inherently difficult as engraving should be intuitively obvious at every step? There should be no need to study the documentation, try experiments, fail, try again, get kind help from experts? Having to do this is “wasting time”, really?
Otherwise you folks just keep making the same point as far as I can see, we get it.
tl/dr
It’s been an interesting time here on the forum for me. I’ve been programming for 30 years. In those circles - a mind crushingly difficult field, it’s like being a foot soldier. You’re so oppressed by what you’re trying to do you just soldier on and have a gallows humor about it all. My son is in college to be an engineer, fun to see him and his buddies have the same experience.
3D art isn’t as hard in that sense, once you learn the skills and develop them to a high degree. But as I mentioned it’s a very difficult mountain to climb to get there. And it’s a literal mountain of never ending work. But other artists all have a good attitude about it, like “well we’re pack horses, just keep on going and put up with the bugs, bad/old software, and difficulties.” Animation is similar. But anyhow, basically getting to do art at all is a privilege, why complain about the little troubles? I never see anybody bitch about their tools (and unlike here, you have to use a toolchain of a minimum of three very different tools to get the job done)
But here in notation circle, gratifyingly people are exceedingly nice and polite to each other, even when somebody takes potshots like I did above 
But, it’s can also be the most exacting and unrelenting group of people I’ve come across in terms of “how it should be done”, at least how they think it should be done.
tl/dr, just shooting off my brain between practice sessions tonight, not worth commenting on …
