Innovative Seamless structural Model building technologies enable to build a large-scale , high-resolution and consistent model.


Enormous Modeling is not

A simply collecting of sub models.

Enormous Modeling means

That arbitrary region could be updated and seamlessly embedded

back into the entire model ,

and the entire evolutional model always keeps consistence.
