Boolean with wireframe on mesh I have a mesh, then I copy the mesh and put the wireframe modifier on it.
Then I select my original mesh and set boolean modifier with the wireframed mesh with the "difference" option. I then hide the wireframe mesh.

Here I expect the wireframe mesh to "carve into" my original mesh at the edge lines. However, this is not working. 


When I use the difference option it just acts as a union, the two meshes are merged together (See first image)
When I use Union the wireframe does "carve into" my original mesh, but it makes holes in it (see image). I want the mesh to still be "watertight". (See second image)


Does anyone know a good way to get the effect that I want?
If this is something like what you're after...




Select all edges, CtrlB bevel, by width, with a moderate even number of segments (here,6)
CtrlKeypad - reduce the selection back to the original latitudes and longitudes
O turn on proportional editing, Connected, Sphere fall-off, small radius
AltS scale along normals.
Select the smallest 'large' face, ShiftG select similar by area > 'Greater Than' to select all the large faces, and I inset them a little..





With  Autosmooth switched on, maybe have a play with the new Weighted
Normal modifier, by face area, to get the look you want without
subdivision.
