Hi Emmanuel,

Thanks for the quick reply! As I pointed out, I'm viewing the room through a HomeComponent3D component. Note that we are talking about a stand-alone application built on top of the SweetHome3D libraries, not a plugin that interacts with the SweetHome3D application itself.

I'd be happy to post the source code of a minimal example - basically it's not much more than the above code inside a main-method, plus the creation of a HomeComponent3D and a JFrame.

There are no stack traces because the program runs without complaints, i.e., no Exceptions are being thrown. It's just that the HomePieceOfFurniture object I add programmatically never gets displayed. Instead, I can see a 1^3m white cube for about one second where the HomePieceOfFurniture is supposed to be which then disappears.

A first guess was that perhaps the model data of the HomePieceOfFurniture was not found correctly, but I made sure that this is not the case, or else the URLContent constructor would complain anyway.

Thanks again for your help.

Cheers,
Thomas
