Ever since finding out about Alied Pérez's SweetHome3D application on the NetBeans Platform, I've admired it very much. (And ever since I've dreamed of designing my next kitchen in IKEA via a NetBeans Platform application.)
Some months ago he told me about its origins: "This project started as a proprietary software for a local furniture business, which ended as a porting of sweethome3d to the NetBeans Platform, with the proprietary part being a plugin for the open source part. In recent times, I have been finishing the proprietary plugins, so the SweetHome3D part has not had major updates. I have to integrate v3.4 of sweethome3d and upload the changes."
I've tried the application a few times but, not knowing much about the domain, couldn't do much with it.

In other words, the application appears to be in good shape. It is also free and open sourced and can be accessed, as I did, here:
