I’ve just discovered Sweet Home 3D. So far, I have to say its one of the best applications I’ve used on Linux.
It’s Java powered and you just download the tar.gz file and unpack it. Once unpacked, run the SweetHome3D file and that’s it. You’re presented with a pretty straight forward interface if you’re used to 3D modelling.
Its logical though as opposed to some 3D modelling apps, right click, choose your tool then left click.
To add one of the many models available, simply drag and drop.
To change the properties of an item, double click on it and modify its properties.
Once you’ve happy you’ve put things where you want them, you can render a photo of the image:

It’s cross platform too as it’s Java. Try it out.
