Allows an application-defined command to override an internal command.
Summary
You can only undefine built-in AutoCAD commands. You cannot undefine the following types of commands:
- Commands defined by AutoLISP ® . This includes ObjectARX™ application commands registered by acedDefun().
- External commands and aliases defined in the acad.pgp file.
If an AutoLISP or ObjectARX application has redefined a command with the same name as a built-in AutoCAD command, the application-defined command is active.
You can restore an undefined command with REDEFINE.
Use the following syntax to run undefined commands or registered ObjectsARX commands:
- To run an undefined built-in AutoCAD command, precede the command name with a period (.).
- To run ObjectARX application commands that are registered by acedRegCmd, precede the command name with a period (.), the command's group name, and another period (.). For example, the MTEXT command can be accessed with .acad_mtext.mtext.
To see a listing of command names and groups of an ObjectARX application, use the ARX command, and choose the Commands option.
