Retired P.E. (Professional Engineer, Texas #35942, Inactive).
Have been using SketchUp for 10+ years … to design and document everything from 100,000+ SF buildings, to SketchUp Components for private use by companies, to house renovations and decks, to parts to be machined, to designs to be 3D printed … and everything in between. I use Enscape for rendering … and Undet Point Cloud Software for modeling from point clouds.
