一种CAD文字样式字体批量替换方法、系统及存储介质
By adaptively recognizing the font pattern of CAD drawing files and explicitly setting it to an empty string, the technology solves the problems of cumbersome, inefficient, and incompatible text style font replacement operations in existing CAD drawing designs, and realizes efficient and reliable batch replacement in single-document and multi-document scenarios.

AI Technical Summary
In CAD graphic design, existing technologies for replacing text styles and fonts are cumbersome and inefficient, especially in multi-document scenarios where manual intervention is required. This can easily lead to omissions, errors, poor compatibility, and an inability to accurately identify SHX fonts and Windows fonts, resulting in replacement deviations and display anomalies.
Adaptive font recognition mode is adopted, and batch replacement is achieved by explicitly setting the font to an empty string instead of deleting the large font field. Combined with the entmod function to modify primitive operations, the symbol table is modified using the entmod function, and the object is forced to be updated by calling the entupd function. Combined with the graphics refresh operation, batch replacement is achieved.
It enables unattended batch replacement in both single-document and multi-document scenarios, improving processing efficiency and compatibility, reducing manual intervention costs, and ensuring immediate verification and reliability of replacement results.
