Google translate: One was tasked to simulate truck freight wagons in full compliance with the actual model. So in the future, all or parts of it went to the training program for railroad workers. I came across an album of drawings, where it was all in her unit. For this purpose it was necessary to master Solid Works, (puppy and squeal of delight from this program I have until now there is no limit). Damn size everything from hole fasteners, rollers bearings for axle boxes to the side frames, bolsters, and neither a rule of thumb, all clearly under the design documentation. As if to depart on the size and moonlight could cause problems with other sub-assemblies and rework it, and headache. Although the headache of cast constructions were plenty who faced tricky drawings, cast parts, I think I understand what it is. The works were many drawings were reproduced almost all the nomenclature of the trolley? including all of its braking system. But it did not stop there, I have already decided to reproduce exactly a freight wagon, which is now at the moment you are watching. The result was one of the detailed models of mobile tools, which I met on the Internet. 16 million polygons spent on the creation of this model. Excurs video: https://youtu.be/wgyXK_aO3dw P.S. The model is not: connecting hose "Frog" and fixing brake.
