I have loaded an stl file and want to do some boolean stuff on it using python API (see code below). First I create the bevel spline and move the end points where I want them. Then I create a boolean modifier and try to union with the bevel-curve. After that want to subtract the union from a cube to make a hole.
But the curve can't be assigned as the object of the union; not even manually and I don't even get an error. Nothing happens. I can set the surrounding cube as the object and that works fine.
So is there something wrong with using bezier curves in boolean modifiers or am I doing something else wrong.

EDIT: I see the same when I try manually. I find this totally bizarre. I have subtracted large objects from stl with 50000 faces each. So why can't I use bool on a simple bend cylinder? It is even meshed! I just happen to know even more about it than just the mesh. So just forget that it's a curved bevel and just use the mesh.
