The Poly Shattering Generator is very straightforward and easy to use application, no overly complex controls/UI, easy to use and control as opposed to the standard shatter effect present in default maya, its so much more straightforward!
3D Models World have a reliable Youtube videos / tutorials and great 3d models.
The biggest fear was that the model is not very detailed and far from the real crane. But when I open the model using an AutoCAD I found that the model was very very detailed even I can directly use it for an FEM simulation in other commercial software. 3D Models World could help you a lot in your projects.
Easily found the 3d model that I was looking for, fast purchase through the phone, I would totally recommend 3D Models World.
