hi Lisp guru's, I have done some searches for lisps that can turn dynamic blocks into static, the one i have found incredibly done well was this Undynamic by MP http://www.theswamp.org/index.php?topic=32681.msg382548#msg382548 (defun c:UnDynamic ( / _get_item _right _make_key _dynamic->static_block _get_locked _get_dynamic_inserts _main ) (defun _get_item ( collection key / item ) (vl-catch-all-apply '(lambda ( ) (setq item (vla-item collection key))) ) item ) (defun _right ( str n / len ) (if (< n (setq len (strlen str))) (substr str (1+ (- len n))) str ) ) (defun _make_key ( collection prefix len / key ) ( (lambda ( i pad ) (while (_get_item collection (setq key (strcat prefix (_right (strcat pad (itoa (setq i (1+ i)))) len ) ) ) ) ) key ) 0 ( (lambda ( pad ) (while (< (strlen pad) len) (setq pad (strcat "0" pad)) ) pad ) "" ) ) ) (defun _dynamic->static_block ( blocks insert len ) (vla-ConvertToStaticBlock insert (_make_key blocks "STATIC_" len) ) ) (defun _get_locked ( layers / locked ) (vlax-for layer layers (if (eq :vlax-true (vla-get-lock layer)) (setq locked (cons layer locked)) ) ) locked ) (defun _get_dynamic_inserts ( blocks / inserts ) (vlax-for block blocks (vlax-for object block (if (eq "AcDbBlockReference" (vla-get-objectname object)) (if (eq :vlax-true (vla-get-isdynamicblock object)) (setq inserts (cons object inserts)) ) ) ) ) inserts ) (defun _main ( document / blocks inserts locked len ) (if (setq inserts (_get_dynamic_inserts (setq blocks (vla-get-blocks document)) ) ) (progn (foreach layer (setq locked (_get_locked (vla-get-layers document))) (vla-put-lock layer :vlax-false) ) (setq len (strlen (itoa (length inserts)))) (foreach insert inserts (_dynamic->static_block blocks insert len) ) (foreach layer locked (vla-put-lock layer :vlax-true) ) ) ) (princ) ) (_main (vla-get-activedocument (vlax-get-acad-object))) ) i am a complete noob at lisp (but trying to learn). could you guys help me somehow incorporate (strcat (vlax-get-property obj 'Name) "_DYNlocked")) into the lisp above (sorry MP for modifying) so that the replaced static blocks retain the original dynamic block name. i am hoping in future i can do a block replace on the static blocks to update them back into dynamic blocks for utilization. thanks for your help! regards, BRC
