This software was designed specially for the AFOLs who want to prepare the layouts of their LEGO® exhibitions. BlueBrick is compatible with LDRAW, "Train Depot Track Designer" and 4DBrix, and was designed with an easily expandable parts database. Its layers feature allows you to better organize your map, and some special layers make annotations and area assignments possible.
