四线的能不能改为大小头（两端尺寸不同而偏移一样）

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
，请给予调试。

gufeng · 发表于 2010-5-19 12:02

抱歉，那个没记得换过来了

你把2楼的第3行的

(prompt "\n now dline width is: ") 换成下面的就可以了

(prompt (strcat "\n now dline width is: " (rtos wwdy 2 2)))

cxs259 · 发表于 2010-5-19 12:13

你好！还是出现：now dline width is: 240.00; 错误: 参数类型错误: stringp nil

gufeng · 发表于 2010-5-19 12:22

不会啊我这可以正常运行的

gufeng · 发表于 2010-5-19 12:29

你下载这个文件试试

cxs259 · 发表于 2010-5-19 13:59

ok了，谢谢！

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。

cxs259 · 发表于 2010-5-19 14:18

如图例所示

gufeng · 发表于 2010-5-20 17:34

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

(if (= wwdy nil)
(setq wwdy 240)
)

2、如果你需要每次在命令行的时候输入，则在前面加上

(setq wwdy (getint "\n请输入宽度:"))

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.
