  You mean it's an open surface, but you want one of the sides to be
considered "inside" in CSG operations (in the same way as eg. heightfields)?

  Meshes are made into solids using the inside_vector directive, and it
should work in this case as well. You just have to be careful with its
orientation: You have to orient it so that it points towards the non-inside
part of the mesh.

  (Eg. if your mesh is an open surface on the xz plane and you want everything
below it to be considered "inside", then a "inside_vector y" should do it.)
