I'm currently experimenting with generating furniture parts, for example a cabinet door with handle and hinges.
I'm interested in this. I wish you good lack!So far it seems to work fine...
That sound good 
You could make a dedicated tread for this.
I'll see if I start a thread about this. A small problem is that it requires Blender at a few stages since the OBJ format I create is Blender. One reason is that is produces no vn lines, so no need to recalculate these. Another reason is that you can generate the same model and by simply changin the line "s off" to "s 1" you can smooth the model(-part). With the Sweet Home 3D export format that would require two different exports with different v* lines.
Another reason is that my current code is in C#, I still have to setup a Java environment. The good thing is that C# is 95% the same as Java so a conversion should be easy.
