Shout out to my fellow spectroscopists. LIBS is awesome. Like, check out the ChemCam. The ChemCam is a laser that shoots rocks on Mars to analyze their composition using LIBS.

As the story goes, Roger Wiens, one of the scientists on the team that made the ChemCam, had a bumper sticker that read “My other car shoots rocks on Mars.” A great teachnique - who wouldn’t want to own it?

“Why yes, I’d be happy to. I’m a professional tall person.”

Yeah, FreeCAD is great, but I can only think of one project that I’ve done where SolveSpace absolutely could not work for the geometry I needed and I had to rebuild it in FreeCAD. But that’s just a product of what I am building: simple things like brackets, knobs, and replacement lids mostly. I don’t need chamfers, drafts, lofts, etc. and I get what I need with minimum of time and effort using SolveSpace.

When I do need those features, complex geometries, or modification of pre-built step files, FreeCAD has never failed me.

No one mentioned SolveSpace, so… SolveSpace. Solvespace is a fully functional 3D parametric CAD solver in a free, cross-platform, open-source, portable, single self-contained executable 10 MB file.

I do a fair amount of hobby 3d printing and SolveSpace makes design and CAD stupid easy. The interface is perfectly laid out, the hotkeys are intuitive, and the capabilities make small-scale projects a breeze.

Now, the program has its limitations, but if I just want something quick and simple, there is nothing better.

Is this it?

I’d encourage you to think about these events as you would a physical injury. A physical injury can hurt for a long time and no amount of recognition or “processing” or “getting over it” can short-cut the all-too-slow healing that needs to take place. It’s no fun and there’s no way to just make it go away.

That said, you can do things that care for the injury while it is healing. I don’t know what these are for you, but for me, I needed to recognize that the people I was angry at were also instrumental in helping me advance.

For example, I had a string of terrible jobs with bad bosses, but that string of terrible jobs led me to someplace that I am very happy to work. Once I realized this, it started getting easier to recognize both that the way I was treated was wrong and that I was also glad that these people were essential to me get to where I am. Even so, it was a long process and physically painful. My anger towards these people did nothing to hurt them, but it was terrible on my health.

I’m sorry you had to experience these things, but I hope they eventually lead you to someplace better.
