How can I export 3D geometry object/scene, camera and textures to a .3DS format? I tried importing the file I created into 3DsMax but it didn't work properly.
3ds is a deprecated file format. For Blender 2.7x export your scene to FBX 6.1 ASCII, this should work immediately. In some cases you have to adjust the settings because it also depends on your 3ds Max version and the version of the fbx plugin installed.
