你可以用 ads_command 调用 linetype 命令加载acad.lin 文件

如果不希望使用命令调用，你可以用纯ARX方法，这些在帮助文件里面都提供了，用 loadline.....就会出来的。需要记住的是，在ACAD下面，没有ARX做不了的，而所有方法都在帮助文件里面可以查到用法

3. AcDbDatabase::loadLineTypeFile Function Acad::ErrorStatus
   
4. 
   
5. loadLineTypeFile(
   
6. 
   
7. const char * ltn,
   
8. 
   
9. const char * filename);
   
10. 
    
11. ltn Input linetype name string (wild cards may be used)
    
12. filename Input path/filename or
    
13. URL of linetype file to load from (path is optional)
    
14. 
    
15. This function loads the linetype specified by ltname from
    
16. the file specified by fname and
    
17. stores it in the database on which this method is called.
    
18. 
    
19. The ltname parameter may contain wild card characters (see the ads_wcmatch() documentation
    
20. for more information on wild card usage). If wild cards are used, multiple linetypes may be loaded.
    
21. 
    
22. If fname is not a URL and does not contain a path, then the AutoCAD
    
23. library search path is searched for the file.
    
24. 
    
25. Returns Acad::eOk if successful.
    
26. 
    
27. Returns Acad::eNullObjectPointer if ltname or fname is NULL.
    
28. 
    
29. Returns Acad::eFileSystemErr if the specified file cannot be opened.
    
30. 
    
31. 
    
32. Returns Acad::eUndefinedLineType if the linetype name specified by
    
33. ltname is not found in the file.
    
34. 
    
35. Returns Acad::eBadLineTypeName if the file contains a malformed record, or a syntax error is encountered.
    
36. 
    
37. Returns an appropriate Internet-specific Acad::ErrorStatus value if a URL
    
38. is specified and the transfer is not successful
