[0055] Reference Figures 2-3 This is the second embodiment of the present invention, which provides a BIM data processing system based on Beidou grid codes. The beneficial effects are verified through system operation.

[0056] Step 1: The file parsing module uses a high-level programming language to write a program to call Revit's APIs, such as FamilyInstance and FamilyName, to parse the RVT file and obtain the electrical physical entity type and name based on the family name and family instance in the file.
