How to trim excess from a curved surface?

I am trying to make a zenfone 2 case. I am trying to cut these from the surface but could not make it, surface trim is closed and only opens when I use knit surface. Is there a way?

To me the case and 3 bosses look like solid geometry in the picture, so 'surface trim' would not work because that's a tool for surface geometry and features, not solids.

If so, 'Delete face' would be the first feature I would try for eliminating the 3 bosses, 'insert>face>delete' and select all the upright faces and the tops of the 3 bosses (21 total faces should be selected). That should leave you with a clean outer case shell.

I think making a sketch on a workplane in space above them that encompasses all the shapes should be done first. Then do an extrude,cut to face option down to the surface they rest on could work.

It can't be done with the "Cut with surface" option ?

try the 'intersect' tool

SolidWORKS Intersect Tool

Also, if you are able to upload your model it will give the community the opportunity to poke around and I bet you will a number of different ways to get the results you desire. It is hard to tell exactly what you are working with from a single picture.

If you are trying to remove the bosses you can also use the split tool and select the inside face as the cutting tool.
