I've been an industrial designer for 10 years and it was very useful. I've used most of the 2D/3D tools, but I wanted to learn SketchUp, so I started studying. I finished it in about 3 days and it was a very useful class. If you listen at 1.5x speed, you can learn quickly. Most of the basic buildings and shapes are finished in the middle. So I think I can quickly become a SketchUp user. Overall, I think it was a good lecture. Inflearn invited a good instructor. I'm grateful and will learn well.
