Sweeping a 2D-profile is not realistic bore/mill .
The sweep of a 2d geometry is not the real result as you would get it when sweeping / lofting a real 3d body.
In Sweep you should be able to select 3D Bodies as well to sweep them along a curve to have the correct / realistic sweep. Then it would be possible to see the undercuts as well.
Many 3D CAD Programs support sweep of 3D-Bodies. Modeling should also be able to do this.
