) <p>感谢二楼相助！但程序出现now dline width is: ; 错误: 参数类型错误: stringp nil<br/>，请给予调试。</p> <p>抱歉，那个没记得换过来了 </p><p>你把2楼的第3行的</p><p>(prompt "\n now dline width is: ") 换成下面的就可以了</p><p>(prompt (strcat "\n now dline width is: " (rtos wwdy 2 2)))</p> <p>你好！还是出现：now dline width is: 240.00; 错误: 参数类型错误: stringp nil</p> 不会啊 我这可以正常运行的 <p></p><p>你下载这个文件试试</p> <p>ok了，谢谢！</p><p>还想再请教一下，能否把宽度240mm,改为任意宽度呢？这样在画钢结构的H型钢或角钢剖面线是就可以一次性画出，减少多次偏移命令。</p> 如图例所示 <p>1、程序开始中的 wwdy 就是宽度，你可以自己修改把240换成你要的数</p><p>(if (= wwdy nil)<br/> (setq wwdy 240)<br/> )</p><p>2、如果你需要每次在命令行的时候输入，则在前面加上</p><p>(setq wwdy (getint "\n请输入宽度:"))</p><p>使用的时候会提示输入宽度，不输入直接确定默认就是 (setq wwdy 240) 这个宽度，看你的设定.</p><p></p>
