I’ve been using freecad for several years and it has improved a lot. I tried fusion and sketchup and a few other “freemium” options but features kept disappearing into the paid section so I decided to stick with something actually free and learn it.
I use the two dimensional sketcher the most. Find some tutorials about using constraints properly and it is very easy to use. The tech draw workbench lets you add dimensions and information in a printable format. Figure out how to do 1:1 scaling with your printer and you can make templates with perfect accuracy in minutes using only a few key dimensions.
Assembly is still a complicated process though. The assembly 3 and assembly 4 workbenches are great but pretty arcane. I don’t remember which one I used last time I did a full multipart plan but the result was great. Basically they let you create anchors on lines and vertexs and such that then interact with each other across parts.
The trouble is in how those anchors interact with their parts. If you round an edge you just made some lines shorter. Was that anchor point attached to that line? Now it’s in a different spot. Essentially you have to be perfect every step of the way and plan ahead or change many things for even a tiny change like a round edge.
With a little practice I’ve been able to get the assembly benches to make great results. You really have to do it correctly though or it all falls apart. The lack of in depth tutorials means you have to make a lot of mistakes and learn from them.
I would suggest trying freecad with either assembly bench. I’m not sure which one would be better suited to your needs. If it doesn’t work for you paying for sketchup or fusion might be a better option. I think in a few years freecad will be very competitive but for now it lags behind on ease of use. Sometimes by a lot.
I’m surprised no one is really talking about asexuality. Sexuality is a spectrum. It’s entirely possible and perfectly fine if romantic relationships aren’t as important to you as they are to other people.
I know people who spend entire nights crying and reinforcing their dogs separation anxiety because they can’t find a partner. Others that are much closer to retirement than college who have never had a serious romantic partner and don’t seek one.
You probably shouldn’t prioritize work over personal life. You also don’t have to be in relationships if you don’t want to. I would recommend keeping an open mind and not getting stuck on labels. If partners and relationships aren’t something you think about a lot that’s ok. If not having that bothers you then you might want to seek professional help to assist in figuring out why you’re avoiding relationships.
Also keep in mind that basically every country on the planet heavily encourages marriage and children so get used to skipping all those options on your taxes and benefits.
