I imagine that for all of us, there are things we'd really like to do, but somehow have never found the opportunity. For me, one of those things is to create a 3D model of rooms in our house for the purpose of playing with furniture placement, remodeling plans, or honestly, just the fun of having a digital model of a real-world house. And were I ever to build a new house, such a tool would be essential. Alas, time doesn't permit such experimentation at this stage in my life, but for anyone who does want to try 3D modeling of rooms, BeLight Software's new Live Interior 3D looks like it would be a boon. It comes with more than 1,000 objects you can place within your own plans or those you modify from the 50 or so editable templates included. It supports Google 3D Warehouse, and can import objects from other 3D programs. You can also work in 2D mode, where it supports automatic dimensioning, automatic floor and ceiling creation, and smart guides. In 3D mode, there's a walk-through mode with multiple adjustable cameras, and you can set the time of day, geographic orientation, and lighting. It's definitely worth a look.
