Hans,

Adding this menu item isn't a big work since the matching service is already programmed .
But before saying ok, I would really like to know some real use case.
Is there any software out there that accepts ZIP files containing OBJ+MTL files except Sweet Home 3D?
If it's only for Sweet Home 3D, isn't the Copy as new furniture plug-in enough?

By the way, we would have to find a better name than Export to ZIP format because this name doesn't say what there will be in the ZIP file and I might create a Export to DAE format one day. [;)]
