Design Technology student teacher needs help :)

Hello, for my final year degree I have to model some stuff in S works,

I've attached a picture for reference.

I am trying to place that sketch of the Atom on the curved surface. If I extrude boss bass it, it works. If I want to wrap it, it says cannot because the sketch intersects etc etc

I want to create Atom shape out of a seperate material so that when I put it into photo360, it will stand 3mm off the surface of the surface of the curve and I can select it as a different material.

Please help

Regards
