.BLD File Association 2
A BLD file is a building script used by Skyscraper Simulator, a 3D building simulator. It contains a building, which includes information that describes the appearance of the building. BLD files also include the name, designer, location, description, version, and camera floor, position, and rotation of the building.
If you come a cross a BLD file and want to view the contents you can open it with a text editor and view it the same way you would view a .TXT file. You can view the name, number of elevators or staircases, floor assignments, and textures for the lobby, windows, carpet, walls, and more.
However, if you want to view the building the file is storing information for, you should place the BLD file in the "buildings" folder where the game is installed. In Windows, you should place the file in the following directory:
After placing it in the directory, open Skyscraper Simulator, select "Other Building..." in the main menu, navigate to your BLD file, and open it.
