Soften tool in sketchup free

I’m trying to model a scooter seat in sketchup free by the push-pull/scale technique. I end up with a blocky shape which i was hoping i could smooth but when i right click and select soften/smooth nothing seems to happen. I’ve attached a screenshhot and a copied link. I know i’m missing something but i don’t know what.

Click the Display Icon, the one that looks like a pair of glasses, on the right toolbar, scroll down a bit and use the soften/smooth settings there.

thanks a lot - that definitely did something.
