System and method for quickly updating geological attributes based on BIM three-dimensional geological model

The invention discloses a system and a method for quickly updating geological attributes based on a BIM three-dimensional geological model, and belong to the technical field of BIM three-dimensional geological models. The system is characterized by comprising the following two modules for data interaction with a water conservancy and hydropower engineering three-dimensional geological modeling system: an attribute matching module which takes an object as a template and completely copies all attributes of the object to another one or more objects; and an attribute searching and replacing modulewhich is used for searching and replacing the object name numbers in batches. The three-dimensional geologic modeling system for the water conservancy and hydropower engineering comprises an EC attribute module, which is used for storing differences of different types of units with different attributes in the EC attribute module through formats of a unit type M and an attribute M for a three-dimensional model, wherein M
