Hi all.
I have a big problem with some attributes that I need remove.
The file attached contain a set of blocks with nested blocks and attributes.
I want to remove all attributes with a window selection and without explode the blocks.
The code below does not remove attributes in nested blocks and some types of attributes are not eliminated at all.
What I can do?
(defun tl_fld (v1 v2) (cdr (assoc v1 v2))) (defun c:attdel (/ ss cnt blk blkdat blknam blktblnam blknewdat blktbldat newblkdat atk_dbug nextent nextentdat nextenttyp endblklst ) (command "undo" "group") (setq atk_dbug nil) ;; (setq atk_dbug T) (if (setq ss (ssget (list (cons 0 "insert") (cons 66 1)))) (progn (setq cnt -1) (repeat (sslength ss) (setq blk (ssname ss (setq cnt (1+ cnt))) blkdat (entget blk) blknam (tl_fld 2 blkdat) newblknam (strcat blknam "_na") blknewdat (subst (cons 2 newblknam) (assoc 2 blkdat) blkdat ) blknewdat (subst (cons 66 0) (assoc 66 blknewdat) blknewdat ) ) (if (not (tblsearch "block" newblknam)) (progn (setq blktblnam (tblobjname "block" blknam) blktbldat (entget blktblnam) newblkdat (subst (cons 2 newblknam) (assoc 2 blktbldat) blktbldat ) newblkdat (subst (cons 70 (- (tl_fld 70 blktbldat) 2)) (assoc 70 blktbldat) newblkdat ) ) (if (entmake newblkdat) (progn (if atk_dbug (princ "\nStarting new block definition . . . ") ) (setq nextent (entnext blktblnam) nextentdat (entget nextent) nextenttyp (tl_fld 0 nextentdat) ) (while (and nextenttyp (/= nextenttyp "ENDBLK")) (if (/= nextenttyp "ATTDEF") (if (not (entmake nextentdat)) (princ "\nCan't make subentity.") (if atk_dbug (princ (strcat "\nAdding " nextenttyp " as subentity " (itoa xcnt) ) ) ) ) (if atk_dbug (princ "\nSkipping attribute definition.") ) ) (setq nextentdat nil nextenttyp nil ) (if (setq nextent (entnext nextent)) (setq nextentdat (entget nextent) nextenttyp (tl_fld 0 nextentdat) ) ) ) (setq endblklst (list (cons 0 "endblk") (cons 100 "AcDbBlockEnd") ) ) (if (not (entmake endblklst)) (princ "\nCan't terminate block definition") ) ) (princ "\nCan't start new block definition.") ) ) ) (if (tblsearch "block" newblknam) (progn (entdel blk) (entmake blknewdat) ) ) ) (setq ss nil) ) ) (command "undo" "end") (tl_$tlp) )
