Skate Park Problem
 

Hello everybody. I'm trying to create a skate park. I was just wonderin':how can I make that bowl effect? I've tried booleans, none of them worked.
If someone can help me, I thanks!!

Booleans is the right way, just get a cube and a cylindar and just select them in a certain order, then do booleans-->difference, and it should work.. The order you select them is key though.

YUP! Thanks!
