Which brings up another thread that would be useful. One on free 3D CAD / modeling software and converters.
I could see a whole array of threads, one each to share experiences with each of the major tools.
I am a journeyman FreeCad user, and would love to have a place to share experiences and skills in that platform. FreeCad is kind of a nightmare--hugely complex, constantly changing, inconsistent interfaces, and buggy. However, it is incredibly powerful and genuinely free. By this I mean, there are no strings attached forbidding commercial use, etc. Very few of the "free" systems have this property. I wanted a system that supported fully-parametric models, has no recurring license fees, was truly free of usage limitations, and runs on a Mac. FreeCad was pretty much the only choice that met all those criteria, so I bit the bullet and dug into it. I am no expert, but I have managed to become reasonably productive. Any other FreeCad fans out there?
