[0069] like Figure 2 As shown, the specific steps of the three-dimensional scene creation and visualization system based on zero-code digital twin technology disclosed in the present invention when used are:

[0070] First, the project creation module obtains the GIS coordinates input by the user and locates the project creation location according to the GIS coordinates;

[0071] Then, the scene editing module builds the corresponding 3D scene at the project creation location according to the scene template selected by the user from the scene resource library. The user only needs to drag and drop to create the 3D scene.

[0072] Then, through the model building module, the corresponding 3D models are built in the 3D scene according to the general models selected by the user from the model resource library.
