请版主老顾修改一个程序
我下载了一个沿三维线段拉伸圆的 lisp 小程序，可在autocad2004中使用，能否修改成可拉伸任何形状实体？类似于auotcad2008中的扫略命令，有劳版主，谢谢。附源程序
(defun c:3dc ()

我改了一下,见下:
(defun c:3dc ()
(setq ss (ssget))
(setq radd (* 0.5 (getdist "\n请输入管子直径: ")))
(setq mmm 0)
(while (< mmm (sslength ss) )
(setq ent (ssname ss mmm) en (entget ent) bb (cdr (assoc 0 en)))
(if (= bb "line")
(progn
(setq p1 (cdr (assoc 10 en)) p2 (cdr (assoc 11 en)) )
(command "circle" p1 radd)
(setq ee (ssget "l"))
(command "rotate3d" ee ""p1 p2 "90" "rotate" ee ""p1 "90" )
(command "extrude" ee "" "p" ent)
)
(if (= bb "arc")
(progn
(setq p1 (cdr (assoc 10 en)) r (cdr (assoc 40 en)) an (cdr (assoc 50 en)) p2 (polar p1 an r) ang1 (* (- (* pi 0.5) an) (/ 180 pi)))
(command "circle" p2 radd)
(setq ee (ssget "l"))
(command "rotate3d" ee ""p1 p2 "90" "rotate" ee ""p1 ang1 )
(command "extrude" ee "" "p" ent)

)
(if (= bb "lwpolyline")
(progn
(setq p1 (nth 14 en) p1 (list (cadr p1) (caddr p1)) p2 (nth 18 en) p2 (list (cadr p2) (caddr p2)) )
(command "circle" p1 radd)
(setq ee (ssget "l"))
(command "rotate3d" ee ""p1 p2 "90" "rotate" ee ""p1 90 )
(command "extrude" ee "" "p" ent)
)
)))
(setq mmm (+ 1 mmm))
)
)
