[ARX程序]：在Arx中如何使用ads_command()函数？

sitrxs

将面face旋转，这样做如何？
ads_command(RTSTR,"rotate3D",RTSTR,"face",RTSTR,"",RTSHORT,
2,RTPOINT,pt1,RTPOINT,pt2,RTREAL,angle,RTNONE);
  其中:pt1,pt2为旋转轴，angle为旋转角度。

在ARX里面，你应该使用：

AcGeMatrix3d类的AcGeMatrix3d::setToRotation构造旋转变换矩阵，然后使用实体的：AcDbEntity::transForm对实体进行变换。

用ads_command（）都能用吗？有的时候不能用，但编译无错，
为什么？？

必须是内部命令。一些自己定义的C：这样的，不能在COMMAND里面用。

编译通过，只是你写的ADS_COMMAND里面参数格式对，编译器不知道这个命令是否是内部的。

10. Question
    
11. I encountered some problems when using ads_command or ads_invoke() from an ARX
    
12. command or from within the acrxEntryPoint() function. Why ?
    
13. Answer
    
14. ads_command() works in two basic contexts in ADS: when operating on the RQXLOAD
    
15. and RQSUBR request codes. In ARX however, it is not working for the ARX app
    
16. message AcRx::kLoadDwgMsg, which is the ARX equivalent of RQXLOAD. It works fine
    
17. for the message AcRx::kInvkSubr, which is equivalent to RQSUBR.
    
18. 
    
19. kLoadDwgMsg workaround: 'int ads_queueexpr(char* lisp_expr);'
    
20. 
    
21. Since it is important to many applications to be able to execute a few AutoCAD
    
22. commands at the beginning of every drawing edit session, this can be
    
23. accomplished by queuing up LISP expressions, including use of the (COMMAND)
    
24. function, using ads_queueexpr(), for execution during the edit session
    
25. initialization, after (S::STARTUP) has been executed.
    
26. 
    
27. Note that the queued expressions are *not* executed during the call to
    
28. ads_queueexpr(); they will occur after your application has returned from its
    
29. kLoadDwgMsg message invocation of acrxEntryPoint(). When using ads_queueexpr(),
    
30. the entered string must be fully expanded and with outer parentheses. Whatever
    
31. was previously passed in as resbuf chains must be converted to ASCII to use this
    
32. mechanism. Multiple calls to ads_queueexpr() from the kLoadDwgMsg callback is
    
33. acceptable because they are queued up in the order of the calls.
