@masao_8 Here is a solution for a simple single selection add and SHIFT-Select to remove. Perhaps this will give you a basis for starting: ;; Function to do a simple Select/Deselect using grread. ;; By PJK - 6/16/2026 (defun pjk-grread-Select (/ done en grl grc grv ss) (if acet-load-expresstools (acet-load-expresstools)) (setq ss (ssadd)) (princ "\nSelect to add objects or SHIFT+Select to remove from selection set: ") (while (not done) (setq grl (grread T 15 2) grc (car grl) grv (cadr grl) ) (cond ((= grc 3) (if (setq en (car (nentselp grv))) (if (acet-sys-shift-down) (progn (if (ssmemb en ss)(ssdel en ss)) (redraw en 4) ) (progn (ssadd en ss) (redraw en 3) ) ) ) ) ((= grc 2) (setq done (if (vl-position grv '(13 32)) T nil)) ) ((= grc 25)(setq done T)) ) ) (if (> (sslength ss) 0) (progn (foreach i (mapcar 'cadr (ssnamex ss))(redraw i 4)) ss ) nil ) )

I would maybe start again, if you look at this https://www.lee-mac.com/polyinfo.html it will find arcs etc in plines So if you want to label Lines, Arcs, Circles and Plines, you may need different code that looks at each entiity and correctly labels. I had a quick google and found a few programs I know that Kent Cooper has something similar to Lee's, but labels each segment. Search also "forums/autodesk".

@mhupp I use Bricscad V25 and it did not work ? Old name stayed there did I miss a step. I tried old fashioned method, it may not be the best solution, if block has attributes then could add a extra sub function to copy the existing values to the new inserted block. Also wants a "Does block exist check". ; https://www.cadtutor.net/forum/topic/99155-insert-a-copy-of-the-block-at-the-specified-point-copyrenameblockv1-5lsp-lee-mac/ ; rename a existing block to a new name ; By AlanH June 2026 (defun c:AHRenblk ( / attreqold bname ent entg inspt oldangdir oldangunits rot scx scy) (setq attreqold (getvar 'attreq)) (setq attreq 0) (setq oldangunits (getvar 'aunits)) (setvar 'aunits 3) (setq oldangdir (getvar 'angdir)) (setvar 'angdir 0) (setq ent (car (entsel "\nPick block to rename "))) (setq entg (entget ent)) (setq bname (cdr (assoc 2 entg))) (setq inspt (cdr (assoc 10 entg))) (setq scx (cdr (assoc 41 entg))) (setq scy (cdr (assoc 42 entg))) (setq rot (cdr (assoc 50 entg))) (setq newname (getstring T "\nenter new block name ")) (command "Bedit" bname "Bsaveas" newname "N" "Bclose" "S") (command "erase" ent "") (command "-insert" newname inspt scx scy rot) (setvar 'aunits oldangunits) (setvar 'angdir oldangdir) (princ) ) (c:AHRenblk) Yes will see flash on screen as Bedit is called.

Having a bit of spare time, I thought I would make a hatch pattern similar to the OS marsh block marsh1.pat

Perhaps you could use the undocumented (acet-sys-shift-down) express tools function within the grread loop? Then you would have to manipulate highlighting with (redraw [3/4]) and use (ssadd) and (ssdel) to update the selection set.

Isn't that how CAD works already? you select something either by mouse clicke or window it will be highlighted hold shift to deselect it the same way. I know if you have to many things selected they are no longer highlighted.

I think you would need to test for 'shift' being pressed and the test for a left mouse entity selection. Do a 'princ' on your grread loop to display what you are doing, shift and select something - which should give you what you want to test for.

I wondered the same.

Simple enough to use getpoint to make it dynamic. Update helper MB with (setq ed (entget (vlax-vla-object->ename newobj))) ;same (setq spt (getpoint "\nCopy to Location: ")) ;add line (entmod (subst (cons 10 spt) (assoc 10 ed) ed)) ;update but why not just copy block then use rb?

Sample drawing with correct layers and what your looking for? For mtext update the entmake with the following. 71 is the text justification defaulting to mid center. use \n for next line. (defun rh:em_mtxt (pt txt lyr ang hgt) (entmakex (list '(0 . "MTEXT") '(100 . "AcDbEntity") '(100 . "AcDbMText") (cons 8 lyr) (cons 50 ang) (cons 7 (getvar 'TEXTSTYLE)) (cons 1 txt) (cons 10 pt) (cons 40 hgt) (cons 50 ang) '(71 . 5) ) ) ) (rh:em_mtxt '(0 0 0) "hello\nthere" "0" 0 0.5) rh:2azimuth can be replace with (angtos l_ang 1 5)

I understand @Nikon I don't like to re-writting lee's code but will give it a try. will need to move new & src to the other side of / and update cb and rb calls. (defun c:cb nil (LM:RenameBlockReference t nil)) (defun c:rb nil (LM:RenameBlockReference nil nil)) (defun LM:RenameBlockReference ( cpy src / *error* abc app dbc dbx def doc dxf new old prp tmp vrs ) -Edit Helper function "MB" at the bottom update entmod inside that with the specified location . Right now its set to 0,0,0

No error handling. just copies existing block and updates name and insertion point. change 0.0 0.0 0.0 to what you want or use getpoint. ;;----------------------------------------------------------------------------;; ;; Rename Block to New point ;; https://www.cadtutor.net/forum/topic/99155-insert-a-copy-of-the-block-at-the-specified-point-copyrenameblockv1-5lsp-lee-mac/ (defun c:CopyRenameBlock (/ ent obj newobj ed newname) (vl-load-com) (if (setq ent (car (entsel "\nSelect block: "))) (progn (setq obj (vlax-ename->vla-object ent)) (setq newobj (vla-copy obj)) (setq ed (entget (vlax-vla-object->ename newobj))) (setq newname (getstring T "\nNew block name: ")) (entmod (subst (cons 2 newname) (assoc 2 ed) ed)) (entmod (subst '(10 0.0 0.0 0.0) (assoc 10 ed) ed)) ) ) (princ) ) --edit rename Doesn't work
