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.
I was not sure if the files are fully supported for all 3D Softwares as advertised. For the moment all was OK! worked! it was easy payment, 3D Models World is a great place (better deals than other websites) I wish they will add more 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.
