[教学]：在AutoCAD中做三维文字...
在AutoCAD中做三维文字...(陈伯雄）1) 写字，例如用隶书体TTF
2) 提取文字线框，用附加程序进行
3) 删除不需要的线
4) 接合成多段线(Pedit-M-All-Y-J...)
5) 一起拉伸
6) 做必要的布尔运算，完成。
------------------------------------------------------------------
程序：
(Defun C:TextB (/ lvl lul lvp lvs lss ViewPL)
(SetQ lvs (GetVar "viewsize")
lss (GetVar "screensize")
)
(SetVar "cmdecho" 0)
(Defun ViewPL ( / vi vw vh vc)
(setq vi (* lvs (/ (Car lss) (Cadr lss)))
vc (GetVar "viewctr")
vw (list (- (car vc) (* 0.5 vi))
(- (cadr vc) (* 0.5 lvs))
)
vh (list (+ (car vc) (* 0.5 vi))
(+ (cadr vc) (* 0.5 lvs))
)
)
(List vw vh)
)
(PrinC "\n要分解的文字行: ")
(SetQ ltl (SSGet)
lvl (ViewPL)
lul (List (Caar lvl) (Cadadr lvl))
lvp (GetVar "viewctr")
)
(Command "mirror" ltl "" lvp "@0,1" "y"
"wmfout" "textb" ltl ""
"erase" ltl ""
"wmfin" "textb" lul "2" "" ""
"mirror" (EntLast) "" lvp "@0,1" "y"
"explode" (EntLast)
"erase" (ssget "p") "R" "W"
(polar (car lvl) (* 0.25 Pi)
(Max (Abs (/ lvs (Cadr lss)))
(Abs (/ (* lvs
(/ (Car lss) (Cadr lss))
)
(Car lss)
)
)
)
)
(cadr lvl)
""
)
(SetVar "cmdecho" 1)(PrinC)
)
----------------------------------------------
结果实例： 我看这样太麻烦吧?无须编程!
最好的方法是:1.输入汉字,设置好字体. 2.命令TXTEXP. 3.将多余的线条删掉,根据结构制作一个个的面域, 再EXT 就OK了! 谢谢陈老师！！
又学了自已不知道的！ 同意2楼意见。

TXTEXP是什么命令？我的CAD2002里怎么没有？ 这是扩展工具里的命令。你有没有装扩展工具呢？ TXTEXP是什么命令？我的CAD2002里怎么没有？ 如何装CAD的扩展命令 谢谢 最初由 Kosilin 发布

直接用CAD的Express中的炸開文字命令Textxp炸開文字。
再使用BOUNDARY命令做出面組。
再伸！
看来您还不知道，您说的功能也是LISP程序，源程序在下面。
您可以比较一下，您不认为还是我的程序更简洁么，在同样的功能下...

好复杂哦，都不想看，算了，这招还是不学了：） 给文字加个thickness如何?不行么?:) 但TXTEXP把文字炸开后，常有把文的某一笔给炸消失了，但不知有没有什么办法解决 按Kosilin []的方法，会做了，在txtexp后，炸开，将多余的线条删掉,根据结构制作一个面域时，我是用pline一步步描的 ,效果不太理想，更好就是用region将其转变为面域后再拉伸，谢谢学友指导！！ 又学了几招，真好，十分感谢 高人太多了！
