I tried using SketchUp 17 for a year, more or less, and I got completely discouraged. I bought a book fo it that has step-by-step training for woodworkers, but it seems that everything I tried to do wouldn't work right, even with the special add-ons for things like biezer curves, polygons with angled sides, etc.
I finally gave up and went back to 2D AutoSketch that I have used since about 1992. Less than ideal for some views, but extremely reliable for the things that it can do.
