Ok guys so I dont know if there is a database that already exists on another website but thought that if not brickset could perhaps take the lead.
With the development of Lego Worlds comes the interesting ability to import models created in LDD and by proxy Ldraw. Obviously this relies on Lego Worlds updating its brick list. However I thought it would be great if Brickset had either links or actual files for LDD or Ldraw that people could download and import into Lego Worlds to use. You could literally plan a whole layout using official sets.
Personally I think this would be a great idea and resource for people to use to populate their world.
