B little Posted April 17, 2012 Share Posted April 17, 2012 I have a previously converted Microstation drawing in Autocad 2011. In the conversion all blocks were given unique names. I would like to edit similar blocks globally. Many of the Microstation blocks look like the standard blocks I use. Does a Lisp routine exist that can select similar Microstation blocks and give them a single name? Quote Link to comment Share on other sites More sharing options...
MSasu Posted April 17, 2012 Share Posted April 17, 2012 This may be one solution; call the PURGE command after to get rid of replaced blocks definitions. ;;; Replace Selected Blocks (17-IV-2012) (defun c:RSB( / blockSource blockTarget nameBlock entBlock assocBlock ) (prompt "\nSelect source block: ") (if (setq blockSource (ssget "_:S:E" '((0 . "INSERT")))) (progn (setq nameBlock (assoc 2 (entget (setq entBlock (ssname blockSource 0))))) (redraw entBlock 3) (prompt "\nSelect blocks to be replaced (press Enter to exit): ") (while (setq blockTarget (ssget "_:S:E" '((0 . "INSERT")))) (setq assocBlock (entget (ssname blockTarget 0))) (entmod (subst nameBlock (assoc 2 assocBlock) assocBlock)) ) (redraw entBlock 4) ) ) (princ) ) There is no validation of source / target blocks similarity (that will be extremely difficult to do programmatically). Please use it with great care! Quote Link to comment Share on other sites More sharing options...
