The model contains a spaceframe. The spaceframe has four coloums and a trapezoidal metal roof. The spaceframe itself consists of horizontal/vertical bars and nodes. It can be used in architectural visualization and also for games. You can download 3-Mesh based formats and one file is as NURBS model. The Blender File also contains the materials. The Materials are made with the blender material node editor (You can change their settings according to your needs)
I can make this Spaceframe in many variations/sizes and even with freeform roofs. So if you are interested please contact me. Have Fun!
