How would you go about adding this feature to this part?

I've gone and added a screw hole info this curved surface by placing a circle sketch on the flat underside and pushed the cut up and through to the curved side.  Worked very well thank you very much!  🙂

My problem now though is how to add a second circular cut to the top of the curved area for the screw head. (Screw heads are wider).  So just a little wider than the existing cut and only a few mm deep from the top down.

I've wracked my brain on this one but am stumped.  Does anyone have a suggestion?

Thanks a tonne... Rob

Hello Robert,

There is no possible to select/use hole feature on curved surface. You can create a new sketch on offset work plane then project existing hole and create new circular profile for cut extrude.

See my attchached video.

Thanks Pavel, I really appreciate that.  It did the trick.  I've attached the (not finished) feature.  It needs improvement but now I know how.

Again, thanks so much!  Rob
