Ok, I got this far: under Mac OS X, choose first Show Package Contents item in the contextual menu of Sweet Home 3D application icon, and go to the subfolders Contents > Resources > Java. I see Furniture.jar, but I can't make any changes to it or even delete it. It tells me "'Java' cannot be modified."
I made a copy of the Furniture.jar file onto my desktop to try to make the sh3f file. (don't even know whether it could work this way) I tried to follow the steps and I tried to tweak a couple, but when I opened the end-result sh3 file in the Furniture Library program there is no furniture.
Of course, I don't *really* know what I'm doing. Other people may be able to get it to work. I've had my Mac for a few years now, but I am still learning its intricacies. Plus, I'm not a programmer, so I'm really not much help.
I do have one concern about this default furniture catalog thing. I've used several pieces of its furniture in my home model. Would they just disappear? It wouldn't be the end of the world or anything, I'm just wondering if I will need to re-measure my real furniture.
