DepthInsight Express Edition 2014:

a structure modeling software developed by our company in

2014 for the international market.

With the self-developed algorithms and based on the

structural model, the framework of any complex structure can

be divided into stair-step grids which can be exported with

files of the international format RESQML. Therefore, thefiles of the international format RESQML. Therefore, the

model data could be shared and exchanged with other geo-

modeling software.
