WHAT IS SKETCHUP?
Google SketchUp is software that you can use to create, modify and share 3D models. It's easier to learn than other 3D modeling programs, which is why so many people are already using it.
WHAT CAN YOU USE IT FOR:
Well, if you're a budding designer it is obvious this is the tool for you. It will give you experience in 3D modeling programs that you will need in your future. If you're not a budding designer, think of SketchUp as a really cool toy. If you're looking to redecorate or redesign your room, you can use SketchUp to see the results before you move everything.
