It’s worse than that. Situations where something causes no harm to literally anyone are few and far between. Even less often you have a full and clear picture of a situation. Usually it’s a choice between who gets hurt to what extent and based on what you know you just try to minimize the damage. You will get it wrong a lot.

Life is complicated and all we can do is to try our best and hope others will too.

• don’t be an asshole
• everything is allowed as long as nobody is getting hurt
• act when you see something wrong
• when you are able to help do so
• in all other cases mind your own business

So am I. I’ve been writing software for a living for almost 20 years, so when I wanted to make a slightly more complicated box to 3d print openscad was my first choice too. Then I tried freecad and hated it with passion. Eventually I ended up making it in solidworks - it sucked the least of the tools I’ve tried.

It’s great when what you are designing is best described as code, but I find it absolutely not worth the hassle otherwise, because even basic things like chamfers/fillets are extremely hard to execute.
