Modelling the train shed in 3D [2]

Actually, I am modelling the longitudinal X-girders. The entire shed structure could be finished soon.

The rivets are omitted at this stage, because their placement on the X, Y, and z axis is very complex and they need some preparation. But they could be added later without problems.

This 3D model is based on original drawings and the error margin is now less than a quarter of an inch.
