Hi Lordfox,

It's because there are errors in the mesh structure, some degenerate faces and some faces with inconsistent normal directions.
The Rhino check command says:
quote:
This is a bad mesh.
Here is what is wrong with this mesh:
Mesh has 4 degenerate faces.
Important things to consider with this mesh:
Mesh has 128 faces with directions different from the mesh as a whole. Although this does not
necessarily mean that the mesh is bad, it can cause problems if you're doing mesh boolean operations with it.
Mesh has 4 pairs of faces that intersect each other. Although this does not
necessarily mean that the mesh is bad, it can cause problems if you're doing mesh boolean operations with it.
You may be able to fix it by using the "unify normals" tool in Silo:

In the next v4 beta which should be released just later today, the sub-d conversion will skip over the problematic faces and give this result:
