Glad to help : )

@GLAVCVSok ,l will manage it, thanks

@ronjonp Yes, thank you very much. It's perfect now! Sorry for explaining it wrong at the beginning.

Code updated above ... give it a try!

@maahee I think you should copy the code again. I forgot to clean up the junk files before publishing it, and it might not be working properly because of that.

The separator character is " " (1 space) and is stored in <->. You will need to change it when necessary.

Try (defun c:crgPts (/ nmarch arch lin p p0) (defun damePts (tx m / c p l l1 i num nm nmdo damePts) (setq num "" nm "") (while (/= (setq c (substr tx (setq i (if i (1+ i) 1)) 1)) "") (if (= c m) (setq l (append l (list num)) l1 (if (not (member nm l1)) (append l1 (list nm)) l1) num "" nm "" nmdo nil) (cond ((and (not nmdo) (wcmatch c "#,[.]")) (setq num (strcat num c))) ((or nmdo (wcmatch c "@")) (setq nm (strcat nm c) nmdo T)) ) ) ) (cons (car l1) (if (/= num "") (append l (list num)) l)) ) (setq <-> " "); change if need (if (setq nmarch (getfiled "Load file" "" "txt" 2)) (if (setq arch (open nmarch "r")) (while (setq lin (read-line arch)) (setq p (damePts lin <->) p (list (atof (cadr p)) (atof (caddr p)) (if (cadddr p) (atof (cadddr p)) 0.0)) ) (if p0 (command "_line" p0 (setq p0 p) "") (setq p0 p) ) ) ) ) (princ) )

I did see a for-purchase program that used a raster image and maybe worked with QGIS, I'll see if I can find it again, the demo video looked pretty good and even split around islands, side branches, etc.. It had a lot of parameters to fill out in a window for what to grab, so still a good bit of work, IIRC.

Are you looking for a LISP, Python, VBA, .NET, etc.? I moved your thread to the AutoLISP, Visual LISP & DCL Forum.

Yes, rename the block first, then use the @ronjonp code.

Probably, for my task, it will be easier to change the @mhupp code. ;; Copy dimension value to another location (x0.001) + text angle = 0 ;; DimCopy.lsp the original / creator mhupp ;; https://www.cadtutor.net/forum/topic/75587-help-with-extracting-text-from-one-dimension/#findComment-597630 ;; modification using AI (defun _DimCopy001:OnlyNum (s / lst out c) ;; we leave only numbers, minus sign, period/comma (setq lst (vl-string->list s) out "") (foreach c lst (if (member c (vl-string->list "0123456789-.,")) (setq out (strcat out (chr c))) ) ) ;; comma -> period (vl-string-subst "." "," out) ) (defun _DimCopy001:SetText (e / ed txt num new r50) (setq ed (entget e) txt (cdr (assoc 1 ed))) ;; change the text to *0.001 (if (and txt (/= txt "")) (progn (setq txt (_DimCopy001:OnlyNum txt)) (if (and txt (/= txt "")) (progn (setq num (atof txt)) (setq new (rtos (* num 0.001) 2 3)) ; for example 4250 -> 4.250 (setq ed (subst (cons 1 new) (assoc 1 ed) ed)) ) ) ) ) ;; ang 0 (DXF 50) (if (setq r50 (assoc 50 ed)) (setq ed (subst (cons 50 0.0) r50 ed)) (setq ed (append ed (list (cons 50 0.0)))) ) (entmod ed) (entupd e) ) (defun C:DimCopy001Txt (/ dim BP LastEnt en obj oldEcho) (vl-load-com) (setq oldEcho (getvar 'cmdecho)) (setvar 'cmdecho 0) (while (setq dim (car (entsel "\nSelect Dimension: "))) (setq obj (vlax-ename->vla-object dim)) (setq BP (vlax-get obj 'TextPosition)) (setq LastEnt (entlast)) (command "_.Copy" dim "" "_non" BP (getpoint BP "\nCopy to: ")) (command "_Explode" (entlast)) (if (setq en (entnext LastEnt)) (while en (cond ((= "MTEXT" (cdr (assoc 0 (entget en)))) (command "_Explode" en) ; convert mtext to text ) ((= "TEXT" (cdr (assoc 0 (entget en)))) (_DimCopy001:SetText en) ; <<< scale + angle 0 ) (t (entdel en) ) ) (setq en (entnext en)) ) ) ) (setvar 'cmdecho oldEcho) (princ) ) Perhaps this code can be made prettier and shorter...

Drawing2.dwg As shown in the figure below: Select multiple graphics in batch and change the R value from 0.2 to another value?

@ronjonp thanks. This code reduces the height of the text, but I need to reduce the dimension value (x 0.001) and insert the text (angle text 0, text height = height of the dimtext).

You could use this to rename the reference in question so that it references a different (duplicate) block definition, which could then be marked as explodable.

Something like this? (defun c:foo (/ d e el m p1 p2) (cond ((and (setq e (car (entsel "\nPick dimension: "))) (vlax-property-available-p (vlax-ename->vla-object e) 'measurement) (setq d (vla-get-measurement (vlax-ename->vla-object e))) (progn (vlax-for a (vla-item (vla-get-blocks (vla-get-activedocument (vlax-get-acad-object))) (cdr (assoc 2 (entget e))) ) (and (= "AcDbMText" (vla-get-objectname a)) (setq m (vlax-vla-object->ename a))) ) m ) (setq p1 (cdr (assoc 10 (setq el (entget m))))) (setq p2 (getpoint p1 "\nSpecify second point: ")) ) (setq e (entmakex (append (vl-remove-if '(lambda (x) (= 330 (car x))) el) (list (cons 10 p2)))) ) (vla-put-textstring (setq e (vlax-ename->vla-object e)) (vl-princ-to-string (* 0.001 d))) (vla-put-rotation e 0.) ) ) (princ) )

This is not possible that I'm aware of. The code above could be modified to explode the blocks selected then make those block definitions un-explodable again.

You may have to Wblock one block, open the wblock, change the explode to "Yes" then rename the block. You can now insert that block into your dwg say deleting the original block. But you will have 2 blocks.

@SLW210 I like the idea of choices in layout name, the main issue is how each company names their layouts or sheet names etc. We used a simple year+projectnumber so a a 2026002-D01 was the name of a layout and single PDF when plotted. If a multi page pdf it would be just 2026002.pdf but we had revisions and a plot date on each sheet.

@GLAVCVS I’ve been testing your latest code. It’s truly impressive. I’m attaching an image of the most difficult area of the last drawing: it’s hard to find a spot where the centerline is not perfectly equidistant. And where it isn’t, it’s always below the tolerance — hats off to you. I’ve also been curious to try the code on embedded geometric figures. As you said, the code fails quite badly here. But when it does work, it returns results that are quite different from those of the @dexus or @GP_ codes, which are much simpler I wonder: why?

I apologize for my English. I use a translator, but I'm not sure if it translates well enough. I have several blocks with the same name. I want to allow exploding for only one selected block. Convert one unexplodable block to explodable block (another translation). Is it possible to leave the other blocks of the same name unchanged?

Ron, I think he thinks to make explodable only selected references and not definitions... Unfortunately, I think this is impossible...

Hi, it's me again... I've implemented lastly coded interventions by @GLAVCVS into my cleaned version... It should work well with user selection of network entities... Still filter for selection is now very robust, but it seems that it should be coded like that (I don't know how to make it better - shorter)... I think that this version fulfills any situation that may occur LINES, POLYLINES (2D-Heavy, 3D), LWPOLYLINES (without arced segments).

Hi Nikon. I'm not sure what you're asking?
