Structures, like most other object, can be examined through clicking on that structure and choosing the examine radial option. What appears in the examination window depends on the status of that structure. When examining factories, a player may see several bits of information. If the structure has been renamed then a "variation of" attribute will appear on the examination window listing the base name /type of structure that is being examined. This window is usually blank under normal circumstances if a structure has not been renamed, however if a structure has a manufacturing schematic inside, it will then display additional information such as the type of item being produced by it as well as the total amount of items that have been produced by that particular factory. This is used as a means of determining how many items are left in the schematic use limit without removing the schematic from the factory.
