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.
I was not sure that whether I would get a 3D model or a kind of software to build up the model, I got timely responses to my question . Also very nice models with a wide variety and at reasonable prices.
The 3D model does work well in our animation software, appreciate the services provided, prompt reply and helpful, the 3D model is nicely done suitable for education and 3D Models World Team is very helpful in providing additional support to cater for customer needs.
