I love it. I do 3D printing as a hobby, but I really dislike the design phase. I usually need simple shapes: boxes or enclosures for electronics. I can find most of what I need on Thingiverse and similar platforms, but there’s always that 20% of things I need to design myself to adapt them to my specific needs.
SketchUp 8 was the easiest software for me to learn, and it just clicks with me. I really wanted to learn FreeCAD, but there's something about the way it works that I just can't get along with, so I keep going back to SketchUp.
Later, I tried all the alternatives: Onshape, Fusion, Tinkercad, and the new SolidCraft, but SketchUp still feels so simple and intuitive to me.
I've had better luck with OpenSCAD for simple things, and I still need to try it out with LLMs. That's on my TODO list!
