In SketchUp, there are no curves, only straight edges and faces. This sphere on the left was created using 24 sides and then extruded. If I zoom in on it, I can see that it actually is made up of straight edges all the way around. The sphere on the right was made up of a circle created using 64 sides and then extruded. Notice how the one on the right looks a bit smoother than the one on the left. So this is going to make the one on the right a bit more information-heavy. If I turn on Hidden Geometry under View, Show Hidden Geometry, I can see that it has more faces as well. Again, it'll look smoother, but it's also heavier in information. So if we translate this into a larger, more intricate model with a lot of visually looking curves, the polygon count will go up. So…
