This invention relates to the field of computer vision and image processing, and proposes a method and system for automatic 3D modeling of 2D engineering drawings. The method includes the following steps: inputting 2D engineering drawings; parsing the context, generating a feature to-do list, and establishing a cross-view spatial mapping coordinate system; extracting the component types from the feature to-do list; obtaining parameterized topological constraint rules for the component types from a preset knowledge base; adopting goal-oriented active probing to search for geometric contours matching the features in the three views, obtaining the geometric primitives and their spatial poses corresponding to each feature; reading the dimension annotations, attaching the dimension values ​​as logical variables to the corresponding geometric primitives, and generating an enhanced structured feature list; constructing an instruction compiler, inputting the enhanced structured feature list, mapping each feature to a feature class calling function in the engineering knowledge base, and synthesizing a Python source code sequence to generate a parameterized 3D model.

This application provides a method for accessing object attributes, an electronic device, and a storage medium. It relates to the field of data processing technology. The method includes: determining object attributes of a target object, where the target object is a feature class instance corresponding to a database table, and the object attributes are used to indicate member variables in the target object; generating a functional interface instance corresponding to the object attributes, where the functional interface instance is used to encapsulate access operations on the object attributes; storing the functional interface instance in a target cache; and, in response to an access operation on the object attributes of the target object, calling the functional interface instance from the target cache to perform the access operation on the object attributes. This application can improve the efficiency of object attribute access.
