I'm an electronic engineering consultant. Upon the recommendation of an AutoCAD user who knew I would not get $4,000+ of value from that software package, I bought TurboCAD many years ago to enhance my skill set and have upgraded periodically.
In addition to standard mechanical CAD (designing/duplicating objects with measurements for fabrication), I use it for documentation, proposals and concept drawings in 2D or 3D in Hidden Line, Photorealistic and, occasionally, some of the artistic rendering modes in Lightworks.
I also design and 3D print jewelry (earrings, so far, but considering other ornamental stuff).
