I remember way back when I started learning SketchUp, I wanted to draw a robot. I wanted the robot to have a nice smooth domed head. I was able to do so… kind of. Initially my geometry looked great and smooth, but as I edited it and changed the geometry, some of the edges were showing up and ruining the smoothness of my robo-dome! Or sometimes, the edges would stay hidden, but I could see each of the facets that made up the metal skull cap, ruining the appearance of a smooth head! Not knowing any better, I discarded countless robot heads in my pursuit of the perfect smooth surface. I had no idea there was a difference between soft, smooth, and hidden, or how simple it was to switch between them.
