Hi, I had a quick question about cutting geometry.

I've got a sketch on a surface as follows: https://imgur.com/a/A6APJ2i

And am trying to cut holes to get a result like this: https://imgur.com/a/NsmaeIk

I've been trying to use the Extrude Cut feature with offsets and thin-features, but was unable to figure it out.

I'd be grateful for your advice.
