The building contains 1.5 tons building materials per square meter, the consumption of labor, material, energy and capacity will be astronomical under so large-scale demolition across the country.
There is a huge impact on the environment in building, consuming 50% of energy, 40% of raw materials, and 50% of the water.
In most cases, the structure is far lower because of material performance factors such as the failure probability appeared not acceptable.

This time, a Nickel material is applied to the model from the native CAD systems’ material list before being exported.
Figure 5 Testing model TABLE 5 Summary results File Formats STEP 3D XML JT U3D Supported YES NO NO NO l Results and Discussion For the 3D XML file, no material information could be found within the viewer program and no word like material or nickel can be found in UltraEdit.
For the U3D file, no Nickel material is found when the CATIA native file is opened with Adobe Acrobat 3D Toolkit, indicating that the toolkit did not import CATIA’s material property successfully.
