重命名/恢复所有动态b
我正在寻找一种方法来替换所有已更改的动力学块（并命名为。例如*U*）。我有一个简单的代码，可以很好地处理各个块。
(defun c:blockrepair (/ #blk)
(vl-load-com)
(setq #blk (entsel))
(blockfix)
);;
(defun blockfix (/ obj #blk)
(vl-load-com)
(setq obj (vlax-ename->vla-object (car #blk)))
(vlax-put obj 'Name (vlax-get obj 'Effectivename))
)
但如果我能让它作为一个“SSGET”来运行，以便能够将多个或所有块恢复为有效名称，那我就完了
有人可以帮助修复或改进下面的代码吗。它留给我
; 错误：错误的参数类型：lentyp nil。
(defun c:test (/ acdoc ss i sset nme #blk)
(vl-load-com)
(setvar "cmdecho" 1)
(if
(setq ss (ssget))
(repeat
(setq i (sslength ss))
(setq sset (ssname ss (setq i (1- i))))
(setq #blk (cdr (assoc 0 (entget sset))))
(blockfix)
(princ)
)
)
) 第一个观察结果是DXF代码0存储实体的类型，而不是其名称；您应该使用-1：
(setq #blk (cdr (assoc -1 (entget sset))))
也需要调整blockfix函数的定义；请记住，ENTSEL返回一个列表：
(setq obj (vlax-ename->vla-object (car #blk))) 非常感谢！！
这似乎现在起作用了。
(defun c:test (/ acdoc ss i sset nme #blk obj)
(vl-load-com)
(setvar "cmdecho" 1)
(if
(setq ss (ssget))
(repeat
(setq i (sslength ss))
(setq sset (ssname ss (setq i (1- i))))
(setq #blk (cdr (assoc -1 (entget sset))))
(setq obj (vlax-ename->vla-object #blk))
(vlax-put obj 'Name (vlax-get obj 'Effectivename))
(princ)
)
)
) 抱歉打扰了。但是你知道如何修改这个，而不是ssget吗。或：
(setq ss (ssget "X" (list (cons 0 "INSERT"))))
我已经准备好了。。
它将创建一个由块有效名称组成的选择集。即该区块称为“TAG_区”。它将选择所有tag_区域块，即使它们已被修改，因此具有名称*U*等。
但不会选择已编辑的不同动态块？ 这就是我要做的。。我唯一能看到的是如何利用我目前（缺乏）的知识。。就是在里面放一个IF，告诉它继续重命名。（如果“blkname”=标记区域。但我的格式可能有点不正确。
(defun c:blockfixall2 (/ ss i sset#blk obj blkname)
(vl-load-com)
(setvar "cmdecho" 1)
(if
(setq ss (ssget "X" (list (cons 0 "INSERT"))))
(repeat
(setq i (sslength ss))
(setq sset (ssname ss (setq i (1- i))))
(setq #blk (cdr (assoc -1 (entget sset))))
(setq obj (vlax-ename->vla-object #blk))
(setq blkame (strcase (vlax-get obj 'Effectivename)))
(IF
(= blkname "TAG_AREA")
(PROGN
(setq obj (vlax-ename->vla-object #blk))
(vlax-put obj 'Name (vlax-get obj 'Effectivename))))
(princ)
)
)
) 知道了。最终使用了李·麦克的注释性参考工具，并进行了一些微调。。
业务端位于“blockfixall”函数的末尾。在需要将动态块重置为实际名称的其他例程之前加载。
(defun LM:getanonymousreferences ( blk / ano def lst rec ref )
(setq blk (strcase blk))

(setq lst (cons ano lst))
