Hello guys, I’m modeling that KEF speaker through CGtuts+ tutorial and we modeled the front, opened holes with some really cool boolean tools. I really like how boolean stuff works on Modo, didn’t see something like that on Maya and C4D. Anyway… I finished modeling the object and when I hit the tab to see it’s sub div it turned out really ugly.

I merged the vertecies, sliced some loops etc. but didn’t changed. Any ideas?
sorry if it is dumb. I started using modo since 301 so I’m pretty new. and thanks in advance…
