Sweep or cut through a piece

[Christin83]

Dear community,

I would either like to sweep or cut through an existent piece…
I try to sweep it but then I can’t get through the edges…
So I thought I cut it but how do I do that?

Please see the screenshot

Many thanks in advance for your help!

Do the same as the curved lip. This time select the resulting body and subtract it.
