As you have seen before, we can create tridimensional sets using objects that already come with Blender.
But, these models are too simple and quite limited..
There are several sites that share 3D models, some for free, some for fee. There are models in different formats, the most common are *.3DS, *.OBJ, *.FBX and COLLADA (*.DAE)
Blender can use many of these formats, but its file type is *.BLEND, that can store models, cameras, lamps, animations, etc.
To use other objects in Blender, for instance, a *.3DS we ahve to import it:
NOTE: Dont forget the importance of the 3D Cursor.
Here i leave a *.3DS file so you can test it:
