sivapathasunderam Posted May 3, 2023 Share Posted May 3, 2023 This is a simple rename block routine (defun c:renameBlock (/ ent elst oldName newName) (while (and (setq ent (car (entsel "\nSelect block: "))) (= (cdr (assoc 0 (setq elst (entget ent)))) "INSERT")) (setq oldName (cdr (assoc 2 elst)) newName (getstring (strcat "\nCurrent name: '" oldName "'. New bloc name: ")));setq (while (tblsearch "BLOCK" newName) (setq newName (getstring (strcat "\n'" newName "' already exists. New bloc name: "))));while (entmod (subst (cons 2 newName) (cons 2 oldName) (entget (cdr (assoc 330 (entget (tblobjname "BLOCK" oldName))))))));Main while (princ)) I want to modify the above routine with getkword function (initget "Main-Title-block Sub-Title-block") (strcat "\n'" newName "' is already exists. Your new block name is: ") (getkword "\nChoose [Main-Tittle-block/Sub-Tittle-block]: ") I wanted to correct many blocks names without typing !

Lee Mac Posted May 3, 2023 Share Posted May 3, 2023 Try the following sample - (defun c:rnb ( / ent enx new opt ) (setq opt '( ;; Keyword . Block Name ("Main" . "Main-Title-block") ("Sub" . "Sub-Title-block") ) ) (cond ( (null (setq opt (vl-remove-if '(lambda ( x ) (tblsearch "block" (cdr x))) opt))) (princ "\nAll target block names already exist in the active drawing.") ) ( (progn (while (progn (setvar 'errno 0) (setq ent (car (entsel "\nSelect block to be renamed: "))) (cond ( (= 7 (getvar 'errno)) (princ "\nMissed, try again.") ) ( (null ent) nil ) ( (/= "INSERT" (cdr (assoc 0 (entget ent)))) (princ "\nThe selected object is not a block.") ) ) ) ) (null ent) ) (princ "\n*Cancel*") ) ( (progn (initget (LM:lst->str (mapcar 'car opt) " ")) (setq new (getkword (strcat "\nNew block name [" (LM:lst->str (mapcar 'car opt) "/") "]: "))) ) (setq enx (entget (cdr (assoc 330 (entget (tblobjname "block" (LM:name->effectivename (cdr (assoc 2 (entget ent)))))))))) (entmod (subst (cons 2 (cdr (assoc new opt))) (assoc 2 enx) enx)) ) ( (princ "\n*Cancel*")) ) (princ) ) ;; Block Name -> Effective Block Name - Lee Mac ;; blk - [str] Block name (defun LM:name->effectivename ( blk / rep ) (if (and (wcmatch blk "`**") (setq rep (cdadr (assoc -3 (entget (cdr (assoc 330 (entget (tblobjname "block" blk)))) '("AcDbBlockRepBTag") ) ) ) ) (setq rep (handent (cdr (assoc 1005 rep)))) ) (cdr (assoc 2 (entget rep))) blk ) ) ;; List to String - Lee Mac ;; Concatenates each string in a supplied list, separated by a given delimiter ;; lst - [lst] List of strings to concatenate ;; del - [str] Delimiter string to separate each item (defun LM:lst->str ( lst del ) (if (cdr lst) (strcat (car lst) del (LM:lst->str (cdr lst) del)) (car lst) ) ) (princ) 1 Quote Link to comment Share on other sites More sharing options...
