/ g' z) E# N7 t1 s. c' G8 }The command function sends an AutoCAD command directly to the AutoCAD Command prompt. The command function has a variable-length argument list. These arguments must correspond to the types and values expected by that command's prompt sequence; these may be strings, real values, integers, points, entity names, or selection set names. Data such as angles, distances, and points can be passed either as strings or as the values themselves (as integer or real values, or as point lists). An empty string ("") is equivalent to pressing the SPACEBAR or ENTER on the keyboard5 ^9 J2 S9 \' P! y5 _! |

! ^" `7 H9 x1 Dcommand 函数向 AutoCAD 命令行直接发送一个 AutoCAD 命令以及对命令的响应。command 函数有一个可变长度的参数表，这些参数必须与命令的提示序列所要求的响应类型和数值相对应:它们可以是字符串、实数、整数、点坐标、图元名和选择集名。角度、距离和点坐标等数据既可以作为字符串传送，也可以按它们自身的数值(作为整数、实数或点表)传送。一个空字符串("")与在键盘上按 SPACEBAR 或 ENTER 键是等价的。

command 函数的参数可以是字符串、实数、整数或点，但必须与要执行的命令所需的参数一致。空字符串 ("") 表示从键盘键入 ENTER 键。不带参数调用 command 相当于键入 ESC 键，这样可取消大多数 AutoCAD 命令。2 c- M j7 s; N5 H& Y
