    众所周知,在天正中可直接绘制箭头,而在AutoCAD中不得。最近我发现一个在命令行直接输入命令就可画出你想要的尺寸的箭头的方法,具体实施如下: D7)(D4S4

      1、首先拷贝下列lisp程序,用ar为名以记事本格式保存,然后改后缀名为.lsp,作为一个lisp程序文件;程序如下: a`#S|'oatC

      2、将ar.lsp拷贝至CAD目录下的support目录下; ?S$i?\Qh  
    XQ%4L-rhN  
      3、在CAD目录下的support目录内找到文件acad2000doc.lsp文件(CAD2002下,在别的版本CAD中可能不是这个名,这是CAD的自动加载文件); %WTEv?I{Ga  
    Ian[LbCWB  
      4、用记事本程度打开acad2000doc.lsp文件,加入一行:(load "ar.lsp") g-c ;}qz  
    lKWPTCU  
      (注意字符要为英文字符) ".^VI2T  
    8K(Z0  
      5、保存后,重新启动CAD,在命令行就可输入ar命令直接画箭头了。
