Maybe another function that could help you...

Nice!

Sure @karfung, but I will leave you to do that (I'm writing from the phone). This is the hint, find it everywhere in the code: (entmake (list (cons 0 "MTEXT") (cons 100 "AcDbEntity") (cons 100 "AcDbMText") (cons 10 pt) (cons 11 pt) (cons 40 height) (cons 50 ang) (cons 71 5) (cons 1 (strcat def_text (rtos lenSegment 2 2) " m")))) Find this part inside: Replace this part: (cons 1 (strcat def_text (rtos lenSegment 2 2) " m")) With this: (cons 1 (strcat def_text (itoa lenSegment) " m")) and you will get the whole integer without the decimal part. I've heard the Durian, but never taste it. If I ever come to Malaysia, I will taste it . Best regards.

@Saxlle Is King of the fruit. Is local product from Southeast Asia. @Saxlle Could remove the decimal .00 (2 zero). Eventually, show the integer with unit m only. Kindly advise. Thanks.

@rlx Thanks. I am from Malaysia. May I know where you're from?

A slightly blunter method I use is to line everything up to a grid spacing (in my LISP I define the spacing rather than the drawing.... just in case) which usually works OK for most thing. A lot of what I do is line diagrams and the polylines are never too far out. - Get a list of points, use Lee Macs round to closest on each point, entmod the line using original and new points. I'd prefer entmod than making a new line just in case something goes wrong in between deleting the original and creating the new, retains all the original polyline info.

just look in autocad help for LUNITS & INSUNITS https://help.autodesk.com/view/ACD/2025/ENU/?guid=GUID-A58A87BB-482B-4042-A00A-EEF55A2B4FD8

I'v never taste the Durian .

You're welcome @karfung . I'm from Serbia. I have made changes to the code, please try it now (I hope I understand your requirements correctly). If it's not, try to change in sub-function "fix_value" the value from "500" to any other to get desired result. The fix function round up the real number into the nearest smallest integer number (for e.g. if you have a 3.70 m, and when you add 0.50 m, you will get 4.20 m, but using fix function which is an AutoLISP Core Function, you will get 4.0 m, also if you have 4.70 m, you will also get 4.0 m). Just an explanation to understand the logic. ; ************************************************************************************************** ; Functions : PLMTXT ; Sub-functions : ang_check_text, fix_value ; Description : Add predifined text with the length segment between two vertices on polyline ; Author : Saxlle ; Date : January 18, 2026 ; ************************************************************************************************** (prompt "\nTo run a LISP type: PLMTXT") (princ) (defun c:PLMTXT ( / old_osmode cur_layer old_nomutt height def_text ss len i dxf_70 plist dataList n k pt1 pt2 midPt ang dist npt pt lenSegment) (setq old_osmode (getvar 'osmode) cur_layer (getvar 'clayer) old_nomutt (getvar 'nomutt) height (getreal "\nEnter the text height <2.50>: ") ;; text height def_text "BD/1:200/" ;; default text ) (if (= height nil) (setq height 2.50) ;; defaul text height, it can be changed ) (setvar 'osmode 0) (if (not (tblsearch "LAYER" "SNA-TXT")) ;; check does layer 'SNA-TXT' exist or not (command-s "-layer" "m" "SNA-TXT" "") ;; make the SNA-TXT layer and set to be current (command-s "-layer" "s" "SNA-TXT" "") ;; set the SNA-TXT layer to be the current ) (setvar 'nomutt 1) (princ "\nSelect POLYLINES:") (setq ss (ssget (list (cons 0 "LWPOLYLINE"))) len (sslength ss) plist (list) i 0 ) (setvar 'nomutt old_nomutt) (while (< i len) (setq dxf_70 (cdr (assoc 70 (entget (ssname ss i))))) (cond ;; the first cond ((= dxf_70 0) ;; LWPOLYLINE is OPEN (setq plist (mapcar 'cdr (vl-remove-if-not '(lambda (x) (= (car x) 10)) (entget (ssname ss i)))) dataList (list) n 0 k 1 ) (repeat (setq l (length plist)) (if (< k l) (setq pt1 (nth n plist) pt2 (nth k plist) midPt (mapcar '* (mapcar '+ pt1 pt2) (list 0.5 0.5)) ang (ang_check_text (angle pt1 pt2)) dist (/ (fix_value (distance pt1 pt2)) 1000) ;; 1000 mm equal to 1.0 m npt (polar midPt (+ (angle pt1 pt2) (/ pi 2)) height) dataList (append (list (list npt ang dist)) dataList) n (1+ n) k (1+ k) ) ) ) (setq dataList (reverse dataList) n 0 ) (repeat (length dataList) (setq pt (car (nth n dataList)) ang (cadr (nth n dataList)) lenSegment (caddr (nth n dataList)) n (1+ n) ) (entmake (list (cons 0 "MTEXT") (cons 100 "AcDbEntity") (cons 100 "AcDbMText") (cons 10 pt) (cons 11 pt) (cons 40 height) (cons 50 ang) (cons 71 5) (cons 1 (strcat def_text (rtos lenSegment 2 2) " m")))) ) ) ;; end first cond ;; the second cond ((= dxf_70 1) ;; LWPOLYLINE is CLOSED (setq plist (mapcar 'cdr (vl-remove-if-not '(lambda (x) (= (car x) 10)) (entget (ssname ss i)))) dataList (list) n 0 k 1 ) (repeat (setq l (length plist)) (if (< k l) (setq pt1 (nth n plist) pt2 (nth k plist) midPt (mapcar '* (mapcar '+ pt1 pt2) (list 0.5 0.5)) ang (ang_check_text (angle pt1 pt2)) dist (/ (fix_value (distance pt1 pt2)) 1000) ;; 1000 mm equal to 1.0 m npt (polar midPt (+ (angle pt1 pt2) (/ pi 2)) height) dataList (append (list (list npt ang dist)) dataList) n (1+ n) k (1+ k) ) (setq n 0 k (1- k) pt1 (nth k plist) pt2 (nth n plist) midPt (mapcar '* (mapcar '+ pt1 pt2) (list 0.5 0.5)) ang (ang_check_text (angle pt1 pt2)) dist (/ (fix_value (distance pt1 pt2)) 1000) ;; 1000 mm equal to 1.0 m npt (polar midPt (+ (angle pt1 pt2) (/ pi 2)) height) dataList (append (list (list npt ang dist)) dataList) ) ) ) (setq dataList (reverse dataList) n 0 ) (repeat (length dataList) (setq pt (car (nth n dataList)) ang (cadr (nth n dataList)) lenSegment (caddr (nth n dataList)) n (1+ n) ) (entmake (list (cons 0 "MTEXT") (cons 100 "AcDbEntity") (cons 100 "AcDbMText") (cons 10 pt) (cons 11 pt) (cons 40 height) (cons 50 ang) (cons 71 5) (cons 1 (strcat def_text (rtos lenSegment 2 2) " m")))) ) ) ;; end second cond ) ;; end cond (setq i (1+ i)) ) (setvar 'osmode old_osmode) ;; restore osmode (setvar 'clayer cur_layer) ;; restore old layer (prompt "\nThe text was inserted!")

@Saxlle Could you do me a favour to amend the lisp code as following, 1). My default layout will be in unit mm. Could the length value of the polyline be divided by 1000? 2). The length value of the polyline is to be an integer, and any decimal is to be increased to 1. Kindly assist to amend the lisp code. Thanks.

I am from Malaysia. Land of Durian, yummy

I've been running 2016 max / Vray on win 11 installed as an in place update from win 10 for at least 2 years now. I did a fresh win11 25H2 installation, now the max installers will not unpack the exe files. When I launch the 001_001.sfx.exe it prompts the unpacker, then just shuts off. I tried shutting off all anti virus and fire wall .. VPN exe, compatibility mode, nothing seems to work, . I was able to install win 10 on a Virtual drive and the Installer worked, so its works, but obvious not an ideal work environment. Anyone have any ideas?

@Saxlle Yeah, this is what I wanted. Really awesome and your prompt response. Thank you. I am from Malaysia. May I know where you from? Thanks.

Hi everyone, I'm a beginner and I’m currently working on an assignment that requires converting an orthographic projection to an isometric drawing in AutoCAD (beginner level). I’ve attached the link to: An image of the assignment question Option 1: my first isometric drawing Option 2: my second isometric drawing could someone please help confirm which option is correct? I’d really appreciate any guidance so I don’t carry the same mistake forward. Thank you in advance.https://imgur.com/a/nN0afna

@rlx Yeah. You have complied with all my requirements. Awesome. Thanks. How about if I plan to change to another unit such as "m" or other. What is the code to be use?

just feed this to the vanilla monster : (ScriptDwg fn (list "LUNITS" "2" "INSUNITS" "4" "LUPREC" "6" ".zoom" "extents")) this part is all pretty basic AutoCad

Hi Team, I wish to create a Lisp code that has the following conditions, 1). Create a mtext above the new draw polyline. The mtext shall be created in every segment of the polyline. The mtext to follows the direction of the polyline. 2). The mtext to be content "BD/1:200/3.0m" above the polyline. The 3.0m is the variable that refers to the length of the particular polyline segment length. 3). The mtext to be layer SNA-TXT and text height 1000. Kindly advise the lisp code above. Thanks.

@rlx Thanks for your reply & assistance. The Lisp code is really awesome. But the units in the newly created file were unitless. Could you able to set the new file with the unit in mm in the lisp code? Thanks.

My $0.05. Why have two edit boxes anyway just display the current value in a single box as you have done. Just edit that value. If you have a limited number of desirable values can put those into make a choice DCL showing the preset values.
