已有程序把线画出来,可是没有线形的,请看下列程序
;定义函数名 (defun c:zhan() ;选择要打开的件 (setq tn (getfiled "原始数据文件(txt;dat;*)" "" "txt;dat;*" 2)) (setq fle (findfile tn)) (if (not fle) (setq fle (getfiled "请选择数据文件" "txt1" "txt;dat;*" 8)) ) (if fle (progn (setq F_ID (open fle "r")) (setvar "osmode" 0) )) ;展点连线程序 (while (setq text0 (READ-LINE F_ID)) ;是否到最后一行 (if (/= text0 "") (progn (setq n (vl-string-position (ascii ",") text0)) (setq n0 (vl-string-position (ascii ",") text0 (1+ n))) (setq n1 (vl-string-position (ascii ",") text0 (1+ n0))) (setq n2 (vl-string-position (ascii ",") text0 (1+ n1)))
(setq dianhao (substr text0 1 n) y (atof (substr text0 (+ n 2) (- n0 (1+ n)))) x (atof (substr text0 (+ n0 2) (- n1 (1+ n0)))) gaoc (substr text0 (+ n1 2) (- n2 (1+ n1))) xianxing (substr text0 (+ n2 2)) p0 (list x y) ) (if (/= xianxing xx) ;_if_1 (progn ;_progn_1 (if (/= xx nil);_if_2 (command "") );_endif_2 (command "pline" p0) ) ;_end_progn_1 (command p0) ) ;_end_if_1
(setq xx xianxing) ) )) (command "") (command "zoom") (command "e")
(CLOSE F_ID) ) ;_主程序结束 |
